I keep one of every gun...sniper, shotgun, pistol, etc. I collect, compare and sell. That's why I laugh when I read someone "needs" more spaces. I do, just to collect but not to use for storing the up ones I use.
In the first one, I didn't play SP after level 35 and it was co-op the rest of the game. It was FUN-tastic! And I tried the slots and won a few things, nothing great. I'll keep at it until it gets frustrating, then I'll shelve it and do something else. It's what I do.
Well, I can't play co-op with my account and because of that, when I'm dying, I usually die. There's no one to help me. As for the game itself, until I find better stuff...which is a 50/50 chance I will...the game will be difficult for me, since I suck at most games. In fact, after the first few days, I offered to sell it to a friend.
Really? wow, that is quite a statement. I may have to pick it up now!
Mine is Halo 3 & Zelda: Majora's Mask.
I played the first one a couple months after release and enjoyed 100%ing it. Except Moxi - that was a messy grind.
