This game is an absolute masterpiece. It's up there with The Witcher 3 in terms of quality - if you're into RPGs and haven't played Enderal yet, drop what you're doing and start downloading it - it's free!
I give it a 10/10 not because it's perfect (it isn't), but because of where it stands relative to the rest of the RPG genre. It operates on Skyrim's engine, so it has all of Skyrim's problems, E.G.: being launched into low-orbit due to stepping on a basket, items/npc's falling through the ground, crashes to desktop, etc. So, save frequently(!) and familiarize yourself with the command console so that you can spawn back something that disappeared, or force a quest stage back to where it should be, etc. The Enderal subreddit is also a great place to ask how to fix something that may be broken.
That said, this game's faults are utterly excusable, and microscopic next to the things it does right. The scenery, music, and gameplay are top-notch. Above all, the story is nothing short of amazing. It takes a bit for the 'hook' to really sink in, but once you progress passed the the beginning parts of the main storyline, you will be addicted like you've never experienced from another game. This is a game that really gets into your head, and will masterfully play at your emotions (I'm a pretty stoic guy, but it pulled even me in!).
The gaming industry needs more developers like SureAI. If any of the SureAI team sees this: THANK YOU! Please don't ever stop making games.
