Got the low cold ending. There aren't much left as end game content. I can go hunting, grinding out the remaining skills. The only two things left is Law of the Berserkers which probably gets me to be kicked out of Goliet, explaining myself to the barkeep girl in Tavar, but I don't have any speech option for that and killing the cleric scientitst for Logan, but I'm not short on money.
The power scaling is really good in this game, starting from the point where you can't fight anything, but the most basic enemies up to the point where even the hardest enemies are no threat.
It also looks like the game might have a decent replay value. Some of the choices are a little bit fake-ish, scaring you that they'll have far reaching consequences regarding the story, in reality, they only change the ending slide show. Others however really have consequences throughout the game. There are also a lot of skill checks early game during dialogues which require specialization. Sometimes it also matters which meat shield you bring with you giving you more favorable results with respected companions or unfavorable with gun happy ones.
The companions themselves are mildly interesting, but not very developed. I'd like more interaction with them besides their companion quests. Romancing however is completely pointless. It adds nothing to the game other than one cut scene (after which I forgot to reequip my armor and was wondering why combat suddenly became more difficult) and some difference in the ending slide show. After you beat the game, I don't know if there is any way to improve their opinion about Jax.
Spoiler
Which is the biggest problem with Falk in my playthrough, since he was already neutral by the end and dislikes a lot the killong of the Hybrid which moves my standing with him to disliked.
I also didn't like that I have to kill Kallax. I learn everything I need to learn from him during our dialogue, I could simply just run away afterwards, but the quest won't move to the next stage unless I kill him.
I also like that the fate of the Hybrid is not a simple choice at the end, but rather a fixed choice based on who you are. What I dislike that instead of it being an amalgamation of your choices throughout the game, like it is with the Domed City, it's only based on your cold level which you can manipulate by going for a low-cold run and consuming enough elex to get the desired outcome.
Over all, the game is indeed a little bit unpolished, but in the role playing department, it beats a good chunk of the AAA action RPGs.
