Sonic's Ultimate Genesis Collection -- Update.

I pretty much spent the first day earning some achievements and unlocking everything that there was to unlock. I spent the second day collecting the rest of the achievements to the point where I have the full one-thousand points. So now that the full game is open to me and all the work is done I can start enjoying the games for themselves. I've already played through E-SWAT: City Under Siege and it was as fun as I remember it being. Decent early 16-bit graphics with great music and really solid Shinobi like game play with an absolutely unforgiving difficulty level. I've also managed to play through the arcade version of Alien Syndrome. I sunk enough quarters into the original machine back in the day and never managed to see beyond the third level. It's absolutely great to at least be able to see it through to the end. So many choices as to what to play next...
