Well there must be some great possible themes out there
better ones still possible with LCD tech...
Titles I'd love to see:
Who's line is it anyway-
"Where the shots are made up and the points don't matter"
~This game would reward by ball time in play (not trapped), and the points would be random till the end, the LCD would generate new 'rules' each ball in play and call outs would be 'appropriate for the game'
Table would be divided into sections with common "Who's Line" games-
When you light all of the ramps the game starts four ball 'Hoe Down' -
High score table would be based on time per ball average and longest ball time.
This game would work well in P3 type machine...
Labyrinth- just a really cool theme- save the day OR side with the Goblin King- (alternate endings)
Two Highscore tables, one for each ending reached.
LEGO- mentioned this one elsewhere but LEGO where the 'theme' could change and the call-outs and points for bashes, pops and rollovers updated via USB... the possibles would me limitless... (or at least fun to build).
Anything else dreamers?
