If you educated your aesthetic vibe enough to acknowledge the potential of trash in video games, then there's nothing better. Even in its most acclaimed titles, the Mega-CD has that trashy feel to offer, at least to those who'll listen: the 15.5 frames in Sonic's bonus levels, the one's during Silpheed's forelast stage, the pixelated scaling effects in Soul Star, the stagnant 30's frame rate in Dungeon Explorer etc. etc.
Granted, there is the 3DO, the Jag, CD-i and what not. But with this SEGA add on, you'll get all SEGA advantages: the good controllers (Saturn quality six-buttons MD-pads), the good developers (Konami, Compile, Namco, Taito, Falcom & Hudson among others) and, in regards to the front-loader, the good looks, too.
There are also neat unexpected surprises, like the only English version of Snatcher, Lords of Thunder's option to adjust the overexposed loudness of the sound f/x to finally enjoy the great soundtrack, speaking of which, there's also the exclusive soundtrack to Another World to enjoy, or the best port of Ninja Warriors beyond the arcades including Daddy Mulk. Now, you tell me. Isn't that worth a measly 300 credits?
