With Knights of the Old Republic being one of the most enduringly-popular and praised Star Wars games (which hasn't been on this list yet! I wonder where it'll end up. Hmmm...), expectations were increasingly high for its sequel. But with executives salivating for some cold, hard credits, the game was rushed through development and released so incomplete that an entire planet was left on the cutting room floor and much of the story was rendered incomprehensible. Still, it was a pretty solid entry for a series that's seen its fair share of nightmarishly-horrible games rushed to release (looking at you, Masters of Teräs Käsi).
Star Wars Galaxies was the first real attempt at a Star Wars MMO - and it was...problematic. Buggy, complicated, not-that-fun (depending on who you asked), etc. It was supposed to be the chosen one - the one who would bring balance to the world of MMOs, then (and now) dominated by World of Warcraft. Sadly, it was not, and had its legs sliced off and its body burnt to a crisp (following this metaphor yet?). And in its place was sent Star Wars: The Old Republic - a Bioware-developed MMO that would try some new things with the MMO world, with story and player choices/morality being touted as the things that would differentiate it from the rest of the herd. And despite solid reviews, it became one of the most high profile MMOs to go from a subscription-based system to free-to-play. Still, it remains the Star Wars game with the most badass trailer of all-time, and that means something (unless you invested money in this game).
One day, someone had a thought: "What if we combined Battlefield with Star Wars?" Like all great ideas, it was simple, brilliant, and involved shooting people with blasters on Endor. And lo, it was a great idea - being able to take part in massive Star Wars battles (both on ground and in space), take control of different vehicles/walking robot chickens, and fight for various factions was everything a Star Wars fan could ever dream of. But what's more, it actually managed to merge the gamer factions of "people who play online shooters" and "people who are still obsessed with Star Wars" into one incredible whole. If someone could do that for Call of Duty and JRPGs, it would be much appreciated.
And the greatest Star Wars game of all-time is, of course, Knights of the Old Republic (aka The Empire Strikes Back of Star Wars games). Made by a younger, less-EA-owned Bioware, the game broke rank with practically every single other Star Wars game and moved its timeline back a few thousand years, before a certain Skywalker family became repeat offenders in toppling intergalactic governments. Not to mention it introduced one of (if not the) greatest side characters ever in HK-47, a murder-droid with a very low opinion of humanity. But more importantly, the game told an original story that felt worthy of the Star Wars name - like the original films, it was something new and fresh and full of discovery. It's the only thing in Star Wars canon that redeems the word "prequel."
Now, everyone start complaining about how neither X-Wing OR TIE Fighter made it onto this list. Shameful.
