I can't say i find the launch titles very impressive - compared with other consoles where there were some pretty damn good things on offer (Wii, DS, 360). The only few that i would consider really good are Oblivion, COD3 and FEAR - hardly platform unique.
I'm sure the rest of them are fun to play - i suppose my biggest quarm is that i'm not a big fan of sports games - but it just seems a bit weak. I mean, a stupidly powerful console like the PS3 and the best launch titles they could come up with are tennis, sudoku and 'Super Rub'a'Dub ' ..
