Sold mine and the 90 odd game I had for it a couple of years ago, really didn't want to get rid of it but I was desperate for money at the time and £150 was £150 badly needed, yoshi safari was good, the jungle book, terminator T2, top gear, mickeys circus mystery, mickeys magical quest, goof troop, porky pig and bugs bunny both had a game, can't remember what they were called now though, but they were good, F zero, rock n roll racing I thought was brilliant, I think I had chip n dale for snes, might have been nes or megadrive though, not sure, Pinocchio, I got this on Christmas day and had finished it within an hour. They were all good back then, not like half the crap they churn out now.
thanks for giving clues to how much they're worth... just what i wanted to know about a birthday present....
I haven't... I sold mine quick as i was desperate for money, it was Worth a lot more than that, and when you look on eBay to find more games you'll find out what they cost today anyway.
the consoles sell for under 30 quid on ebay... 
Yeah, things go down in value as well as up, with everyone putting it all on eBay and places like that they are going to be worth less, when I sold mine Mario kart was selling for £50 with no box, the jungle book was about the same as well, I also had timon and pumba which I sold separately for the same sort of money, as soon as anything goes up in value people stick it on eBay, then make them worthless again.
