It's only $9.90 at Frys but I dont know if i should buy it because only 5 games use it so far. Should I get it? Also, does it work good?

5 games?

1 - Animal Crossing: City Folk
2 - The Conduit
3 - Wii Speak Channel (if that counts)

OT: yes

Well if you own those two games then yeah, otherwise buy some food :)

There is also, NHL 2k10, Endless Ocean 2, The Grinder. Maybe Gladiator A.D, Tatsunoko Vs Capcom, Call Of duty Modern warfare

Has Tatsunoko Vs Capcom been confirmed?

At that price you may as well. Its not great, its not even good, but it works well enough.

Wii Speak on a fighting game? If i wanted to hear someone else swearing i would rather swear myself...

nope.

oh ok, the way I read it I thoguht 5 games that were released used it

hold out on it for a bit until there are more games that use it especially if you are getting the game or not.
