What do you want in MW2 for the Wii.
Here's a list I made off the top of my head:
-More modes
(ex. search and destroy, capture the flag, headquarters, team tactical etc.)
-Every modern gun that exists
-More challenges
(ex. pistol kills, humiliation, basically what 360 and PS3 have like Dog Challenges or w/e)
-Several maps
-Cool looking prestige symbols.
-Different kill streaks rewards, maybe more like we get something for 10 kill streak instead of just 3,5 and 7
-nice perks
I'll repost if I can think of any more ideas.
