I definitely preferred the Gamecube exclusives and also the Gamecube itself had far faster CPU performance to PS2 which showed in many games. I had a few multi-format titles on both and the Gamecube might have had shorter and lower quality video sequences but general gameplay was often better. Anyway for exclusives on Gamecube there was also Mario Kart which I still really enjoyed and Monkey Balls plus of course the amazing Roque Squadron games that still impress today with how amazing they look. None of those PS2 exclusives you have listed were important to me. I did play Gran Turismo a bit but its not a game that I put huge hours into and yet its probably a game you really need to. I'm struggling to think of PS2 games that were important to me. When I set up a system to play retro games there isn't much I put in the PS2 folder. Half Life comes to mind, maybe the first Killzone. Some of the classic 2D shooters, R Type Final I think its called. Maybe the original Timesplitters and the Gradius games. Some of the highly reviewed PS2 games I tried to get into but they weren't quite my thing. I'm sure there were many good PS2 games but actually games that were really important to me on PS2 don't seem to be that many. In fact for that generation I think there are more important games for me on Dreamcast and Original Xbox. The PS2 was the weakest console of that generation for me even though it was the most successful.
