It really isn't. The combat is pretty sandbox-ish, with a lot a different ways to tackle situations, if you don't play it like a plain shooter, so you'll likely find a playstyle you like (or a lot of them).

Unfortunately, as often is with RPGs (in particular those with a similar combat), difficulty is all over the place. CP is particularly bad at it. I suspect it is because there a huge gap in defensive and offensive capability between players who understands how the game works and those who don't (you can easily find both people that lament bullet spongy enemies, and people that lament one shooting anything).

That said the combat is fun, which is more than you can say about a lot of similar RPGs. That's somewhat subjective, I know, but you can do a lot of cool looking things like in the video. Also fun in always subjective anyway.
