Will I misses out all the action of the new batman game called Arkham Asylum?

Everyone is so excited for the new batman that is coming out and I misses out on all the action because I bought dissida for the psp and I was so stupid to buying it and so far i'm not liking it so far and I want the batman game instead of this game I have for the psp . Its getting more good reviews so far for the batman game. I think more people buy the batman game instead of dissida for the psp.|||My husband had it reserved, and bought it the day it came out...he loves it so far!
