What the hell is this argument about at all anyway?
RE4 was released for GameCube first, with it's release the Exclusive deal between Nintendo and Capcom was ended.
The deal WAS, REmake Resident Evil 1, make Resident Evil Zero, and Resident Evil 4.
Capcom brought the game to Playstation 2, with slight graphical twitches, new in-game tweaks. From what I have heard the Ps2 version is based off the PAL GC version.
The Ps2 version has the P.R.L. 412, Separate Ways, and New Costumes for Ashley and Leon.
GameCube is not a 'kiddy' console. The Resident Evil series for starters, some may be ported, but they are on the console. Zelda is not a child's game anymore, with technology increasing, the creators can make longer/bigger games with larger/more advanced plots.
The Metroid Prime saga is not for children, and Viewtiful Joe is quite difficult.
Eternal Darkness also comes to mind, Killer 7 which may be on Ps2 also, but it IS on GameCube.
Now back to topic:
This is easily the greatest looking Playstation 2 game ever made, with real people involved. Ratchet & Clank, Jak & Daxter, and Sly Cooper come to mind as animated characters. This will go down in Ps2's history as one of the best games, ported or not. The small slowdown is as little as the GameCube version, i.e. in the beginning in the village, blow up 7-8 villagers with a grenade for a small bit of slowdown. Load times aren't that horrible, Separate Ways gives Ada a REASON to be involved at all. I don't have the P.R.L. but from what I hear it is great.
That should cover anything that derailed this thread.
