Not dedicated, but not a bad conversion either...and I've seen a ton of Superstars conversions (ops seemed to really like this kit).
Superstars and Wrestlefest compliment each other (being in the same series and all). I've heard preferences for both games. I haven't gotten my Superstars/Wrestlefest cabinet together, so it's been a while since I've played and compared the gameplay details of both.
Superstars is definitely not an "investment friendly" game. You purchase it because you enjoy the game, not so much to resell later. 1-300 for a dedicated seems to be the norm and it seems you'll be hard pressed to get that back. I've got more than 300 in mine and it's just a pile of NOS parts sitting next to a stripped dedicated cab. Some games seem to be like that.
