I have some money and i am deciding on getting one of the three that follow:

Transformers the game
Need for speed pro street
a wireless headset


what do you guys think?

I think that the wireless headset is a joke. I have yet to play Transformers but I have heard nothing but good comments about it. I would say go for your #1 pick!

I don't see the need of upgrading to the wireless headset (Presuming you have the standered wired one)
I would personally go with the games don't know which though haven't played either...But it's up to you at the end of the day.

I would check the reviews of the games first to see how they rated at. And do you have the standard headset? Because that would play a part in the decision.

none, all lame imo. ive heard good about Transformers, and i liked the movie much (it was very mechanicly inclining) but i doubt movie based games much. never been a fan of NFS and if you have a headseet, then you don't need another unless it's broken. Lol, just my opinion.

Don't buy Transformers for sure, games that are based out of movies usually suck. But you never know. Try checking the game scores in other sites like Crwler said. Have fun with money dude!

Go for need for speed.
