Woops.. not so new.. this one came about in late 2008
Check the date - that item dates back to September 2008.
Old Chicago casino itself dates back to before this though, and was still MGS powered. It was run by the MiniVegas group, although did not seem to be actively promoted. My attention was drawn to it as it featured in the infamous "illegitimate play" episode in the summer of 2006, where there was a "mass confiscation" of winings, even from a few player who did NOT take a bonus (Hence the "illegitimate play", as opposed to the usual "bonus abuse")
Uh oh, does this mean it's not a place to become a new member at then? - I was considering trying it out...without taking a bonus.
