I really really enjoyed playing on my bro's N64. Diddy Kong Racing was simply amazing. I don't know how much of that is to do with the fact it was my first real experience of console gaming, or my age mind.
Tiger Woods 2005 - 2007 on the PS2 was great fun, but that's because my neighbour enjoyed it so much, so many an evening was spent playing it.
My dance mats were also great on my PS2.
But it's got to be the Wii for me. Wii sports is a perfect party game, so many fun hours spent playing it with friends / family.
