I bought a Dreamcast (I think it is) off a mate with loads of games and accessoris, not got round to playing on that either, are they anygood.
Sadly no is the answer to that
Never really took off in the UK, PlayStation won that little battle

Dreamcast was way better than the playstation2 - stable online gaming before any other console had even thought of it (and it was free - sadly the servers down now) graphically superior to the ps2 in every way and some fantastic arcade games - i had both and the sega machine was lightyears ahead - the old Betamax/VHS story, better tech pushed out by better marketing, killed off sega as a hardware company - sad because they really understood what makes a great console - just no one bought it 
I bought one! Great console, although it did have a few gimmicks (like those memory cards that were supposed to be little hand held games in their own right, in which the battery lasted about 5 minutes..)
I do like to buy dead-end tech, though.. bought the DreamCast, that killed it. Bought the GameCube, that killed it. .. :lol:
I have a PSP for mobile gaming - it was great.. I just haven't turned it on in about two years

I'm very tempted by the new version that's coming out, though!
(Also have a PS3, 360 & Wii.. none of which get turned on with any kind of regularity)
