the dreamcast was the biggest let down, it had all the hype when it came out and was supposed to be the next big thing and it just failed.
for those people saying the psp was a big let down, how sad are you, its a games console that has perfect graphics, the ability to play mp3's, view images and play movies. And your trying to say that Sony are wrecking it well no I dont think they are, there just trying to stop people like you downloading your ISO's and playing the latest and best games for free, and if Nintendo and Sega and everyone would let them legally put the emulators on the system wouldnt they have already done. Homebrew and Emulators are great but how the f*ck can you say that these are the best things about the PSP, whatever system is released you will always pick faults and call it sh*t, heres a challenge....you go make the perfect system and along with it all the emulators and games, see how far you get.
Some people are just never happy
getting back on track though, dreamcast for me was the biggest flop but like all systems it was great but just didnt live up to its hype.
