DE Star Wars has a different feel to it than other games, just like the other DMD Data East games do as well, in my opinion. I'm not sure if I like that or not.
It's a fun game but as usual back then when people used good really famous iconic classic movie themes the game itself falls short to other games with weaker licenses or original themes ironically. Happened all the time with video games in the NES/SNES era, I know all of the movie console-video games sucked particularly bad (let alone not living up to the hype), and many agree. Never seemed to get it quite right, perhaps it's just because the bar is set so high from the start though. Lots of opportunity for disappointment.
Anyways, enough rambling: It's not so bad but I feel like it could have been better, but I mean, compared to some games, it's pretty fun. I haven't played it that much though or really learned the ruleset of the game.
I'm not a major dedicated fan to the franchise but if I was I feel as if I could overcome my little gripes with it and definitely enjoy it/own it for that reason and others. It just feels a bit different compared to DMD games at the time produced by other companies, yet still even feels different than a Data East alphanumeric game. Not sure what it is, and not even saying it's a bad thing, but definitely make sure you give it a whirl quite a few times on location somewhere to make sure you're really set on it.
I've never played (or even seen, AFAIK) the other one.
