Should i just buy 360 or get wii games?

i really am not 100% satisfied with my wii if you know what i mean. there are not really great games. but i still like it for ssbb and i have some gh games and mario kart. but im getting 299.99 ( pro system ) 65$ ( halo 3 plus gow 1) 25$ ( ethernet cable ) 8$ ( xbl 1 month ) $20 ( play and charge kit ) and $25 for an extra wired controller. all together for the 360 and stuff it will cost $443about. with that money i could get about 9 wii games. should i get xbox 360 plus accessories or just stick with my wii and get games.
