I agree with the fact that mario is maybe more fun then most psp games out there but....mario has been around for a long LONG time and is starting to wear a little thin, dont get me wrong i like mario but soon they are gonna run out of ideas for him (and they cant just keep repeating mario carts even though its legndary) The battery on the psp has never been an issue for me playing tony hawks at friends for atleast 2 hours (WI-FI ROCKS) and still have time to listen to lots of music without even being on the last bar.
I think sony will bring out some realy awesome games for the PSP and when that happens nintendo with have serious competion
