Hey there MiceChat,
I had the chance to take a day at Six Flags Great America during a recent work trip to Chicago. I'll be posting some pics sometime after the weekend (and in some upcoming Weekend Updates) but wanted to give my thoughts on the park for anybody who is interested:
The day started off kind of bleak with the threat of rain moving in. I had pre-purchased my flashpass so there wasn't really anything I could do.
Thankfully the rain stopped about 10:30 and I was able to get in all of the rides. In fact, I did many of them multiple times (I think I did Whizzer and Raging Bull 6 times each).
I think my favorite moment was my first ride on American Eagle, it was on the backwards side since the Red side wasn't open yet. I had no idea of the layout of the ride so it was truly a unique experience.
Overall I think the park is probably the most "well rounded" of any of the Six Flags parks, although SFFT comes close. There aren't really any coasters that "blew me away" but just a lot of "FUN" rides, which is totally awesome.
Superman:Ultimate Flight - I've now ridden all three of the US versions of this. Nothing unexpected here but still a fun ride.
The Dark Knight - I actually enjoyed this. Sure it was a mouse in a box, but it was fun and I give them effort for going for it.
Batman:The Ride - I think this was my 6th Batman? Again, nothing new here, but nice to ride the "originator".
Ragin' Cajun' - Thank God for the single rider line on this as the ride didn't open until later in the day.
V2 - This was actually my first "true" impulse (I've only ever previously ridden V2.5) and I enjoyed this. Took rides in the front/back/middle and all were good.
Spacely Sprocklets - Credit ride, but fun for the kids
Iron Wolf - Not as bad as Vortex at California's Great America, but not great either. Nice to get a ride on it before it's gone though.
American Eagle - Both sides were cool, I was happy to get both sides in. Is this the longest queue line in history though?
Demon - Had a semi-enjoyable ride I guess.
Raging Bull - Fun ride, my 2nd B&M hyper, I think I like Nitro better, but still a fun ride.
Viper - Didn't care for this much at all, only rode once. Loved the layout but the ride was rough I thought.
Whizzer - This was the surprise of the day for me. I absolutely loved it. I think I rode this about 6 times and could have ridden it more.
Little Dipper - What a classic, I'm lucky that I caught this right when it opened because when I walked by later it was over an hour line.
I also rode the Sky Tower, Train and Log ride, all were fun great family rides.
Being that this was the other original "Marriott's Great America" park it was interesting to see the subtle similarities between this park and it's California Cousin. Overall, I'd say that the Illinois park is much better themed, much cleaner and has MUCH better rides than the current California's Great America. You can see some things that are very similar, but there are differences.
