I am really enjoying the game so far. I'm pretty engaged with it. My only gripe is the lack of information during crafting and how the whole inventory/equipment system is designed. There's some minor stuff here and there like quest markers and mounts, but I generally dig it. Exploration and questing is super fun and so is building up an army a la Suikoden. Combat isn't fantastic, but it's fine.
Gunstar Heroes, Sonic the Hedgehog 2 and Mega Man X are three that I'm guaranteed to play at least once a year.
I'll rotate Final Fantasies but I tend to play FFX and FFIV way too often.
I still consistently play The Last of Us multiplayer.
I'll return randomly to games like Picross 3D, Burnout Paradise, Mortal Kombat 9 and Rhythm Heaven Fever. With certain friends we'll go back to Worms Armageddon, Lemmings, and You Don't Know Jack.
I don't replay Mario and Zelda games as much as I'd like to. I play the hell out of each one while I'm in the moment, but I just haven't replayed much of them recently. I'd also like to go back and play Kirby Super Star or Brave Fencer Musashi more often.
Pick up everything. Even common herbs such as Elfroot will run low pretty quickly. Which means more running to and from destinations and less using mounts. Mounts are better for trying to run up hills though.
