Thinking back on all of the awesome gaming I did on PS1, PS2, and PSP, makes me a bit sad when I look at how "few" PS3 games I have.
Personally, gaming's best for me was on SNES, PS1, and GC. But, PS2 has the most room for me to explore many many more games I never played. So, though PS2 is ending production, my adventures with it are far from over. :)
My hopes for new games that appeal to me are getting sparse these days. But, on the bright side, games I have overlooked gens 3-6 are still plentiful, and I still have stacks of games for those systems I haven't even opened yet, so it might be time for a back log marathon!!! :D
