Right now i'm currently playing Guilty Gear X2 #reload for the 360. I downloaded it and its a lot of fun, if not a little strange. I'm playing that and Fire Emblem: The sacred stones. Both of them are great, but there both full of BS 
.
Guilty Gear is well... very unique 
. Its a very colorful game and the soundtrack is cool, but this isnt a review so i'll just stick to personal opinions. My favorite character is Ky Kiske, he is something like Raiden from Mortal Kombat mixed with a justice loving swordsman. Google him, he's pretty cool. Although like I said before, this game is full of BS. Where its all in japanese I cant understand much of the battle dialogue, and the storyline for each character is confusing, but heck its from Japan, what can I expect. But it is a lot of BS. I'm playing it on normal and some people like friggin rape me(not literally). That and I dont know what the heck a EX Gold character is.
Fire Emblem: the sacred stones for the game boy advance, is an excellent game, but its full of a whole crap load of BS. I'm talkin you could probably fill the Grand Canyon with this games BS. If you wanna get my point i'll tell you a funny story. In this game if your units die, they go bye bye forever. In other words, make one mistake and your screwed. Now on to my story... I spent maybe an hour or two playing a single battle. I ended nearly every enemys life. There were two enemy generals in the battle, one had already been slain by my mage. So I figured i'd kill the other general and end his pathetic life. I gave my strongest soldier a dragonslayer lance because the guy I had to kill rides a dragon. Well I attack him and hit like a 32 or something and the guys max life was maybe 45. So the enemy general was near death, and I didnt want him that way, I wanted him dead. So I send another unit to attack the wounded general. I had a 70+ hit percentage and woulda done 20+ damage. He had like a 2 percent chance to hit a critical. Guess what happens. My guy attacks first. I miss and the enemy pulls out a BS attack and hits a critical. Whoops, my guy ends up enjoying a nice spot in heaven(or more likely in hell hehehe) By this time I was ready to chuck my controller(I had a game boy player) into the TV then use it to murder a helpless puppy.
Currently wish I could play... Supreme commander for the 360 or C&C3: Kanes Wrath for the 360. I'll probably get Supcom at the end of the week, if its in stores by then.
