Final Fantasy Tactics at 100%. Twice.
Hundreds of hours played in Fallout 3 and Fallout New Vegas.
I think those are the games that define me as a player. I love turn-based games where I have time to consider my best strategy against a difficult opponent. That's why I love chess, as well. I also love games which have all these difficult hidden characters, items, and abilities that you have to really try hard to uncover. Likewise, FPS games like Fallout 3/NV are some of my favorites because they allow you to use your own tactics, with your own character build. I dearly love building a sniper/stealthy character and taking out Deathclaws when I'm under-leveled.
I think the other thing that defines me as a player is how deep into crafting and money-making I get with MMOs. I got quite wealthy in Ragnarok Online (though not compared to the botters), and quite wealthy in WoW and the last Star Wars MMO. That's something I really like to do, though most MMOs ruin crafting by making it something only raiders can really profit from. Screw that.
