I have very little to add, but still feel like throwing my two cents about the games mentioned:
Kotor 1: I can't be objective with this game as it was my first (good) wrpg, but there's a ton to love, even if the game starts out slow and the plot is classic Star Wars cheesy.
About your specialization complaint, let me say that that you have nothing to worry about: you can develop your PC any way you want as you'll get more than one specialist character covering every skillset you could need (most of them before finishing the first planet). There ARE a few missable things if you choose one specialty over the other, but that's kind of the point of a game that lets you develop your character however you want, right?
Kotor 2: Wow, Touchfuzzy really nailed it better than I ever could. Kotor 2 was an extremely rushed job as it had to be launched at the same time as one of the Star Wars prequels, IIRC. The game has many problems* and yet, its' stellar writing, complex and deep characters and interesting take on the SW universe make it a memorable experience.
Seriously, even if you don't want to play it
take a look at a let's play of it, you'll be doing yourself a favor.
*And I DO mean many: it's unfinished(and filled with partially cut content), unpolished, buggy, unbalanced (there's a ton of overpowered items and skills) and poorly paced (particularly the first and last chapters)...though most of these things have been solved thanks to fan-patching.
Septerra Core: I could never get into this game (though I got very close to the end of it), I found it's battles incredibly dull, despite having a somewhat unique spells and attack systems, the characters left me equally indifferent. Also, there were a several points in the story that required either dumb luck, a walkthrough or classic adventure game style pixel hunt in order to find out how to proceed.
Anachronox: In many ways, this game is very similar to Septerra Core, the battles are also very slow and more than once you're kind of lost on what to do. Still, it's definitely more streamlined in both aspects than SC, it's cham, wit and great ambiance also contributed to win me over. I don't know if it's your style, but the game has a great sense of humor, that might not be as apparent at first sight.
Have you tried playing the original (Snes and Genesis) Shadowrun games? They're quite interesting, though flawed games. BTW, from what I've read it seems that Dragon Fall is actually a huge improvement over its predecessor that adressed most of the complaints fans had with the original game. Though that's just hearsay, since it doesn't run on my computer. T_T
I don't know, if it counts, but Wizardry 7 and 8 follow a scifi space war story with a very 90's-ish cartoon style, though the bulk of the game is played in a medieval-esque world. Mind you, there ARE spaceships, robots, holograms and other genre staples even early on, but most of the game looks and feels pretty medieval. Not to mention that the game is old school as hell.
Though it isn't sci-fi, Arcanum: of Steaworks and Magicka Obscura (I used the full name because there's another game called Arcanum), offers a steampunk styled d&d world, with the awesome open-endedness and great writing of all the Troika games
Well, maybe it was more than two cents.
