You have a DI already, which many folks consider a close cousin to Wonka. I own a DI LE and JP Prem, and they play very differently. JP is crazy fast and to me more demanding - the roaming dinos ensure that you always have some time pressure. I like having the variety along with my other games. Personally I feel like there's a lot of overlap in DI and Wonka in terms of gameplay - not a bad thing per se, but it's fun to mix it up.
