About as lasting as Wii Sports I'd guess although it's early days. I do think Sony should have included a few more events, more modes and perhaps even online, but I guess there was a trade off between launching and taking forever to have knockout titles.
I'd guess at this point playing it competitively will be where it's legs really are vs the AI. That's where I've had the most fun.
Try to be reasonable... its easier than you think...
