Well, I've just recently traded in my Xbox and all my games with it, so I'm stuck with playing my games on Steam, which is actually pretty damn sweet.
I've neglected this game for a while, and truth be told I haven't started it up yet, though I will today. You're probably all familiar with it, but if you aren't, you basically play as a wizard (no shit) and you cast spells by using different elements. No more hotkeying from a skill tree, nope. You combine fire and earth and you make a fireball. You combine some other elements and make these magical bomb things (I forget the combination). It was really difficult the last time I played, but still really, really fun, and I have no idea why I didn't finish it.
Another game that I started playing that you're probably familiar with. It is basically a spaceship simulator except you don't actually fly your ship around but you're in charge of the crew, the different systems on the ship, the power, etc. It's actually really fun and addicting, despite how repetitive it can be.
Sort of like that.
Besides those I've also been playing through Fable and I'm trying out LoL (we'll see how that goes).
