This is my first Xbox of any description.
Probably keep the exclusives, of which there were 14 out of the 50. Two appeared on PC, so they don't count, so that's 12.
There's a couple of multiplats that I have on PS2 as well, so I'll keep the Xbox versions of those since it was a more powerful console. I assume the multiplats tended to be better on Xbox from what I've read.
I've got a boxed Starwing SNES, plus half a dozen other games and a Nintendo Scope 6 I'm collecting on Saturday, all being well.
