Sonic rules, and so does this collection.
The only really important thing to remember when assembling a compilation of classic games is to make them spot-on, to-the-pixel, perfect recreations. Unfortunately, the Mortal Kombat 3 emulation on Midway Arcade Treasures 2 suffers sever sound glitches when fatalities are performed. Worried yet? There's no need to: all the Sonic games presented here are faithfully recreated in their entirety, without any glitches.
Plus, we get a solid amount of unlockables and extras. If you play Sonic 3 and Sonic and Knuckles enough, you'll unlock the kick-awesome epic, Sonic 3 and Knuckles (see my review of Sonic and Knuckles for more info on this game).
If you're too young to remember the old school like me, or you want a trip down nostalgia lane, pick up this collection right now.
