What determines lastability? It's different for everyone.
What Star Trek has in its favor is lots of modes, multiple levels per mode, different ways to approach them resulting in different awards. IMO it's extremely challenging to get thru all Level 1's to get Kobayashi Maru Multiball...it's a satisfying goal to shoot for. On top of that you have the challenge of finishing all the Level 2 and 3's! It's going to take lots of play and practice to get that good - so there are attainable but super challenging goals to keep you coming back.
Anyone who says all the modes are the same hasn't played the Level 2 & 3 variations...that's where they get totally different.
