Well maybe its better if we wait for the "official release"
1st of all, its a rom. cheating will be far more easier(as far as editing fake pics and whatnot).
2nd of all, its illegal, so you shouldn't be using it in the first place.
3rd, the official release may have several (major/minor) differences then the rom, meaning all your times that you sent would turn into doodoo
4rth, some people don't have a pc as that runs as nice and smooth as yours, meaning they cant play roms, thus giving you an unfair headstart
5th Thats about it
so its alot better if you just wait for the official release
Besides, if somebody important from sega happened to stumble across this site, and notice that there were many people using the rom rather then buying their product, then they might try to shut us down or something (chances of happening .001%)
But still, you get the point
It's just alot better to wait for the release, plus roms can give you an unfair advantage. sometimes it may slow down your computer, thus slowing down the game, giving you a better chance to perform quite an accurate rom.
So in short, wait for the game to come out, then buy it! Besides, you'll help out sega as well, then maybe they can make a sonic advance 4!
