Quoted from Yoko2una:Define "young". My son is 11 and just getting tall enough (and still on a small stool) to see and time upper flipper shots. On our ST (and when we had SM) he usually skips the upper flipper shots. Not a big deal on ST, but essential on TMNT.
Also I'd say the game is very fast but not frustrating. Ours is parked next to ACDC, and that's fast as well and my son is starting to put some real good games together. He just needs to learn TMNT more as the rules aren't as straightforward.
If your kids are younger, the theme may be ideal, but the gameplay may be too fast and rules a bit hard to remember (but at least you can play as a team).
Thanks this info helps a lot! I've got a 10, 7, and 4 year olds. Mainly thinking about my 10 year old as the 7 year old girl only plays with her American Girl Doll pinball, and the 4 year old loves to play but obviously just constantly presses the flipper buttons (which oddly helps him get to Deadpool's multiball pretty quickly). The co-op mode really might be what sells this game for me as it can convince the kids to play more and not just be frustrated that my turn is taking too long.
