As a previous owner of the previous two starcrafts I had high expectations as I couldn't wait to try out the campaign. I don't play ladder that much in the game, It's really not my thing. I was able to reach diamond league for one season during HOTS but didn't really care (the seasons reset every single month). Now onto the campaign itself. It's really fun and immersive (as to be expected). I also wasn't fond of the different choice of units you could choose because it's blatantly obvious which one of the 3 was the best to choose. The Co-Op campaigns are really easy; you could actually solo them on hard-easy. On brutal though it actually requires the help of your buddy to kick butt and do the bonus objectives as well. If anyone is struggling on the campaign or to do achievements then mass void rays. The campaign gives you access to the PRE-NERFED void rays + they get a new passive range buff as well. I'd give it 5 stars if my game didn't randomly crash on me from time to time. No other blizzard game crashes on me and I haven't crashed once in HOTS or WOL so it's probably a thing they have to patch up. I wouldn't say it's worth $40 as you're mainly buying it for the single player campaign but it's definitely worth it if it goes on a sale.
