You can play two portable Sonic games in one bundle with Sonic Advance & Sonic Pinball Party Combo Pack. Sonic Advance is a classic Sonic-style 2D platformer. Dr. Robotnik has concocted a diabolical scheme, and it's up to you to stop him. Play as Sonic, Tails, Knuckles, or Amy as you collect Chaos Emeralds and thwart his nefarious machines. You'll need all the help you can get, because this all-new quest gets more challenging by the minute with tons of puzzles and traps. With Sonic Pinball, Amigo the monkey and NiGHTS join Sonic and his friends for some lively pinball competition, multi-player party games, and of course, lots of ring gathering. Once you've built up a nice pile of rings, head to Casinopolis for Roulette, Slots, and Bingo.
