I love my ps3 but really I would like to see some valve support. Update the orange box all of it, fix bugs and update TF2. I would also like to see left 4 dead their upcoming title which is a pc and xbox360 exclusive.
Other than that, Im really really confortable with the ps3. But I love valve games I really do and they dont show us the love heheh :P
Since the time of ATARI, Commodore and early PCs I am big fan of Adventure games. I recall the best adventure game series ever ... The Monkey Island . I would like to see some more games of this kind... more quality puzzels, ideas, good story than action, fights and scary creatures. I enjoyed also Drake's fortune adventure recently... it was /for me/ the first right step to this genre on PS3. but the game had still too straight-lined story.
