Knights of the Old Republic (KOTOR)
If you're a fan of Role Playing Games and Star Wars, then you have no doubt at least heard of Knights of the Old Republic. If you've never played it, go buy it. It's worth every discounted penny. Bioware made KOTOR back in its hayday of Dungeons and Dragons style RPGs such as Neverwinter Nights. Bioware has always been great at storytelling and they put a lot of Star Wars love into this title. It was the first RPG for many folks out there and considered to be the first real RPG title for Star Wars as, until Disney took over, followed canon.
