Mass Effect 2 (360) - this one was a bit soured for me considering I bought the special edition of the game and still haven't been able to get the DLC codes to work. I really hate that EA make you jump through hoops just to fuckin register the damn thing. So for now I'm just trying to concentrate on the game and not let that ruin my experience of it.
My initial opinions are that the shooter aspects have definitely been improved upon and polished up, but it really seems like less of the RPG elements have been included (or their importance has been dumbed down a bit) The cover system frustrates me, its nowhere near the Uncharted 2 level, or better yet the Gears of War level of things (I still think the GoW games have the best cover systems I've played)
It's pretty damn addictive at times, I'm only around 10 hrs in so far, but quite liking it.
Shin Megami Tensei: Devil Survivor (DS) I've been slowly getting into this one, its a hybrid srpg/turn based rpg with a pretty cool demon recruitment and fusion system. Pick it up if you like SMT games definitely, or are just looking for a good story in a DS RPG. You'll need some patience though, as some of the battles have kinda cheap failure requirements (wrong word, but hopefully you know what I mean)
Anyway, I really wanna get back to ME2 heheh. Till next time =D
