Now I think it's fairly self explanatory were you a PS1 fan or a Nintendo 64 fan?
Now I had both, a PS1 at my mums place, and a Nintendo 64 at my dads place, so I played a lot of both.
PS1 - Loved the thing couldn't get me off it, that is unless you were my older brother
, anyway Me and my brother used to play loads of the good old WWF games, Toca Touring Cars games, the early FIFA games and so many more. I was obsessed with Jonah Lomu Rugby, played it religiously, although I can't find the disc anymore which is so disappointing.
Nintendo 64 - Loved it although because I didn't have as much access to it as I did my PS1 i loved my PS1 more, but still when I was at my dads me, my Brother and my step brother would hire Conker's Bad Fur Day whenever we got the chance and play it constantly while we had it, when we couldnt hire that we played Duke Nukem 3D and the Mortal Kombat games had loads of fun and wasted so so many hours on the thing.
It's such a hard decision for me to make as I loved both but I'd have to say Playstation wins for me, mainly because I had more access to it and therefore played it alot more plus it had my all time favourite sporting game Jonah Lomu rugby on it.
