This place is fun fun fun! First of all, I'd have to say, its not as good as DisneyQuest was, but since their departure from downtown, GameWorks is a great alternative in Schaumburg. If you have a group of friends, and are willing to take the drive over to the burbs, its located right by Woodfield Mall, and it's a great place to have fun. They have lots of shooters, classics, and new games, plus, a few BIG games that are fun. For $20 you get a card with 100 points, which should last about 2 hours of gaming enjoyment. Check it out, I highly recommend it.
P.S. try to go on a weekday, cuz on the weekends, it gets pretty packed.
Pros: Good parking
Cons: a bit crowded on Sat.
