DC is by far the best system ever created, why?
No modchipping or mods or swap tricks needed for anything
easy game burning
Original games/system is cheap as hell now
Excellent homebrew community
Best games ever, these games never seem to be defeated, i was playing SC and i rented SC2 (for all 3 systems) and i was left with this empty feeling inside, i went back to SC and returned the SC2s without buying them
Has the Most soul, you will never see such a large collection of great games, the DC is almost pure soul, its got Capcom Vs. SNK, Street fighter, the last blade, etc.
None of the games suck, I have yet to see a DC game which i didnt enjoy, even the small time Tetris clones keep me entertained
CHEAP VGA support, its about 5-10 bucks, any other system you better get ready to slap down 80+ bucks
Excellent controller, great for ANY genre, it just plain rules (1st person shooter takes some time to get used to, but once you do, it just plain rules)
Has that great Arcade feel to it, Sometimes you need a break from all these ultra realistic games, you just want a great, simple yet challenging, arcade style game, but if you want realistic, DC has that too!
Compact, this is one of the smallest consoles ever made (not including handheld of course)
The list goes on and on and on, best system ever, just plain rules
