I picked up a Dreamcast, after years of not playing any video games, just as it was announced that Sega was abandoning the hardware business (around early 2001). What followed was a few years of catching up with the software and collecting as much as I could. It's always a fun hobby to ignore a system until it's in its final throes, because you can survey the best without slogging through the worst (necessarily).
I like the Dreamcast because of the broad range of titles it offers. Like a lot of people on CAG, I have an affinity for off-the-beaten-path games. Polished and coloful actioners like cannon spike, mr. driller, crazy taxi 1 & 2, power stone 1 & 2, jet set radio, the cool action RPGs like Shenmue 1 & 2, Record of Lodoss War, and all the incredible 2D fighters like SF Alpha, 3rd strike, marvel vs capcom 1@2; not forgetting some flat-out weird titles like seaman and typing of the dead (all worth owning).
Yeah, some of these games are available on other systems, some with extras beyond what the DC offers. Yeah, the controllers are not as ergonomic as the dualshock(tm).
But there is a quirky, polished simplicity to the overall design of the console, and not coincidently, the design of many of its games. This is a wonderful thing.
