I don't have the space for pins that no one EXCEPT my 5 yo wants to play!
He's already playing most of our pins (inc. EJ, TNA and JP2) - his problem is that he gets frustrated when he finds it hard. He doesn't know what shots to make, he can't get the ball under contorl long enough to start much off... short version, he's a beginner. It's especially tough for him because his brother is a decent player (for an 8yo).
So, it's less theme than pins with a relaxed feel and longer play times. Often, these are pins with lots of easy returns to the flippers, wide-open shots and so on. Hence, why we thought DP might be a good choice - it's notable for being on the 'easier' side, it's bright red, I've personally reached a mini-wizard mode (once) on location, and there's a multiball that can be started by hammering L'il Deadpool a bunch of times
Toy Story would be perfect as well, I realise, as that's pretty-much what it was designed for (and I had a reasonably good time with it at the Dutch Pinball Museum), but I think there are only about three in the UK and they cost megabucks...
I'd never considered Getaway, although
@MadMonzer liked it at Pinfest, apparently
