I've also sort of been opposed to the limiting "Top 5" or "Top 10" format of the end of the year lists. So much so that, at the end of last year, I resolved to make a list of every game I played and finished during the coming year (that was released during that same year) so that I could more easily remember them when it came time for Top 10 lists. I would then make a top "whatever the total number of games was" list and post it. Is that hipster-ish? If so then I'm a hipster.
It's kind of a flawed system if you were to look for my favorite games because it doesn't list any games that I played the year after they came out. Two such games that won't make it to next years list because of this is Mighty Switch Force and Xenoblade Chronicles, the latter of which I'm quite enjoying at the moment. Another example is Duke Nukem Forever which I played, but didn't finish (because it's terrible).
As for your list, I like it. Ghost Trick was phenomenal, and even if it in my mind belongs on a list of "games that don't need sequels" the status of the main character have changed enough that a new game could be really different and interesting so long as enough work was put into it to make it so.
I've only played a few hours of The Binding of Isaac but boy is it a fun game. Despite playing Super Meat Boy last year I was somewhat put off by its style. This was before I played it. Having played through a lot if not most of SMB with only keyboard controls the lack of joypad support (by this time I had purcased an Xbox controller to be able to play Bastion properly) didn't bother me at all. It also opened me up for the idea of playing other Rougelikes, even if I have yet to try one out. It might also have been the reason I spent a bunch of hours playing the original Zelda on my 3DS yesterday...strange as it might seem.
I've spent over 200 hours on Dark Souls, starting different characters and trying slightly different playstyles before settling on my favorite one and finishing the game. It, like Demon's Souls before it had a lot of elements that I miss from other games, namely the way your character's strength is balanced to the giant monsters he's facing, but also smaller stuff like costumizability. Some experiences were lost, for example I never had one as grueling as struggling against the Mindflayers in Tower of Latria, perhaps in part because of more generous checkpointing and a easier upgrading system, or perhaps because the game is simply easier. I still regard Dark Souls as the superior game and if not for all its annoying jank it could've easily become one of my uncontested favorites.
Rock of Ages never appealed to me no matter how many trailers or quicklooks I saw of it. Maybe I should try it and give it a chance, but nothing about the gameplay as it looks from outside seems like it would acually be "fun" to me. I've never played any of the Dead Risings either, not so much for a lack of interest as I simply lost interest and forgot about it before I could try it out.
Clash of Heroes might be my #2 for the year, because its fundemental mechanics were so easy to grasp I could play it with a wide variety of people, both people who play videogames regularly and people who didn't. This really elevated its appeal for me. As for the story, I got mildly invested in the premises of the 3rd and 4th chapter and thought that the characters were well done. The ending was weird though. So weird how the whole evil-possession thing ended without any consequence for the people involved, as well as Jeezebeth's and Aidan's relationship never had any conclusion.
I still have 2 Ace Attorney games that I've yet to finish, the thought that someone can play them over and over again boogles my mind, but then again it probably gets a lot easier after the first time. That said, if I recall correctly Miles Edgeworth 2 won't be localized outside of Japan, that must be such a bummer.
I also had a desire to play Chrono Trigger once the Endurance Run really got going, although I never put in the effort to find a playable version (Virtual Console might have one?) and now that they're at the end of the quest that desire has subsided significantly.
If I could name one thing that defined videogames for me in 2012 it was the fact that it was the year where I started playing a lot more smaller games, either portable or downloadable, and stopped buying some of the bigger releases for the sole reason that they were big releases. It has hurt me in the past where I've bought games like Arkham Asylum or Dead Space, good games that I lacked any passion for and while enjoyable, they were far from engrossing to me. I decided to change that this year thus I've avoided their sequels. Deus Ex was in a similar position in that I was ready to get invested based on the hype, but something put me off once it was released and I managed to hold off of getting it, maybe I really would have enjoyed it?
I was all set to get Skyrim yet somehow between 200 hours of Dark Souls, 58 hours of Zelda and watching coverage of it I lost interest. Maybe I'll pick it up eventually this year, or maybe I'll just "wait for the next one", something I kept telling myself while looking at the recent Fallout games.
Phew~ that was quite a rant, this is what happends when you don't run your own blog I guess. You ruin others's
Ok this final part might seem like it came a bit out of the blue but have you played any of the Oddworld games? When you mentioned games you should at least try I thought back to these puzzle platformers (platform puzzlers?), in part because they've been on my mind the last few days what with the release of the HD remake of Stranger's Wrath. If you enjoy puzzle games the first two are pretty inventive and are only like 3 bucks on Steam.
