It wasn't just the ending. (So far I've only played as a full male human.) But there are parts of the game that seem to be missing. First of all not counting the tutorial area there are only 3 "hubs". Your pc and other charcters seem to get information off screen
Spoiler:the Edwen reveal anyone? The first time I found out was in the final level when speaking to Mathras. Or how about the elf prince dying off screen, the death of Peeler?
There are a couple of bugged quests as well.
The music however is great, VA is mostly great except for the female Vulcan. Characters are okay, some are more forgettable than others. Combat would be better if enemies towards the later levels weren't hit sponges but it's serviceable. There's also a lot of running back and forth so having unlimited sprint is great.
It was still fun for me (with cheats, though skill points and feat points makes leveling pointless since you don't actually get any stronger at higher levels) but this game has some very glaring flaws.
