Nostalgia can be such a wicked cunt. I was mad for revisiting the old consoles too at one point, and brought out the old PS2 along with GTA3. About 20 minutes into it, I couldn't help but compare it to GTA5 in every possible way, and well, it got put back. If you are going for 16-bit love with the Megadrive or SNES, just get yourself an emulator an play it on yer PC. As someone else said, I feel the N64 has dated pretty badly (really blurry textures), the DC has some great games but you're heading to Ebay to get games for it, and the Gamecube isn't worth getting if you have a Wii for backwards compatibility. So if you feel the need, go for a PS2, and cex will serve you with a shitload of games. But it's never as good second time around
