Pros:
+ somewhat fresh take on the turnbased tactical with new mechanics (no or rather very limited overwatch, risk-reward of debilitating combat injuries turning into strengthening scars over time, character building via sets of playing cards)
+ I like the "Weird West"-setting very much
+ great narrator voice
+ new take on storytelling with loosely but significantly interwoven episodes (a bit like some Jim Jarmusch-movies), each with roughly 5 missions
+ art and graphics style fit the atmosphere greatly
Cons:
- several scenario-breaking bugs, having no manual option to keep several saves means having to start the episode anew (most of these bugs seemingly can be avoided by completing a scenario in one sitting without exiting, which takes about 2-3 hours)
- stuttering even though system should be able to handle the game effortlessly (I found a handful of different workarounds on teh web, in my case activating VSYNC and avoiding Alt-Tabbing seemed to improve things significantly)
- achievements are also buggy, not always activating when they should
- these issues most probably will never get addressed, since most of the development team quit the company and there have been no dev-answers on the forums for years
Overall:
The bugs and resulting need to complete scenarios in one go are quite annoying to me as a father of two with very limited gaming time. However, I enjoyed the game so much, that I actually did just that.
A note on the difficulty:
Seemingly, the lack of a proper overwatch presented a major obstacle to some people accustomed to the X-Com-mechanics. As a very methodical and careful X-Com-player, I had no problems whatsover and rather breezed thorugh most of the base game on the hardest difficulty. Positioning and flanking are key, don't let yourself be goaded into battles of attrition shooting though cover. Retreating and luring enemies into the open or teaming up to get one character into a flanking position works wonderfully most of the time.
