For some reason, LucasArts was always assaulted when going out of their "comfort zone" (really what people thought that was). I remember how there were many topics hating on "Pipe Dream" solely because it wasn't a Graphic Adventure.
Yet people seem to love Zombies Ate My Neighbors...
I remember things differently, where certain games seemed to get more praise than they maybe should have, just because they were published by Lucasfilm Games / LucasArts. And they had a lot of creative titles during their fledging days. A personal favorite of mine is BallBlazer, and Rescue on Fractalus is an all-timer, as well.
I still hum the BallBlazer theme on a regular basis. It will absolutely get stuck in your head
A damn shame those seem to be as lost in time as they are! There's a Famicom version of BallBlazer that is pretty good (and affordable!) but Fractalus is more or less locked to the Atari computers of the time. I keep hoping for some sort of "Lucasfilm Classics Collection" published by Nightdive or Digital Eclipse. Maybe someday...
Funny thing about Pipe Dream is, it wasn't even developed by Lucasfilm Games! They handled some of the PC publishing, but I think Bullet Proof Software had the console rights...? Regardless, I remember seeing that game everywhere, and remember it fondly as an exemplary title of the "Puzzle Craze" of the time.
Back on the "hidden gems" front, I'll toss out another title published-by-Lucasfilm-but-not-developed-by-them: Night Shift! It's a pretty original one, where you work the night shift (get it??) in a factory that is constantly cranking out Lucasfilm-branded toys... and also constantly breaking down. The screen scrolls vertically as you climb up and down the 'works to flip switches, press buttons, turn off alarms, hop on the exercise bike...
Came with some pretty cool in-universe packaging and paperwork, too. Maybe not the best game - so not a true "gem" - but certainly a creative one, and pretty hidden, I think! That has to count for something, right??
