This list will be a short one, mostly due to my not usually bothering to play games that I'm not too interested in for one reason or another due to my minimal time and money. But these are the games I didn't care for for one reason or another in 2011.
While not a huge fan of the Splinter Cell games, I do find them enjoyable. I like stealth gameplay (can't wait for Thief 4!) and was really looking forward to this one. After playing it for a couple hours, though, I just couldn't get that into it. The controls just didn't grab me and the prerequisite of having to do some sort of close-quarters-combat take down in order to be able to do a mark-and-execute action didn't sit well with me. It's been sitting unplayed for a while with the intention of getting back to it, but I've just got so much good stuff to play that I haven't bothered.
Ok, I got peer-pressured into this one. I've never been a fan of the console Call of Duty/Modern Warfare games due to the controls. May dad and both of my brothers had this game so I felt it'd be fun to play with my family. Only problem i, they were all prestiged and level 800 or something so, by the time I was around level 20, they were done with this game and moving on. I played the single player campaign briefly and haven't played it at all since. I just can't get into the controls... Yes, controls are very important to me and my experience of enjoyment. And I also realize I'm a minority on that point. :)
I'm a huge Bethesda fan, a huge Fallout fan, and I appreciate what Obsidian does. And at first, I was gung-ho about New Vegas. But as it continued on and on, it just wasn't grabbing me in any remarkable way. It's not a bad game, it was just a "blah" game. Maybe I'll go looking for all the crazy mods and see if that helps any.
I LOVED Dragon Age. I bought that game twice, once on the PS3 and then again on the PC with the Ultimate Edition with all of the DLC. I bought Dragon Age II on day one and had huge expectations. And again, the game itself isn't bad, persay... but compared to the first Dragon Age, it's utter crap. If it had been called "Adventures of Kirkwall" or whatever, it would have gotten a pass. Is that fair? I dunno.
Just because I helped make it doesn't mean I can't hate it!
EDIT: People were wondering about this, so feel free to check out my other blog posts. Many go into my game development career, and Blackwater is mentioned in a few of the later ones!
So, there you go, short list, like I said. And I don't think these all actually came out in 2011 at all, but oh well. I still have a bunch of games I've not played through yet, but maybe they'll end up on my best or worst list of next year.
