Hi mate!
Honestly such a brilliant game.
I have no idea how many hours I sank into this when it first came out but I think I'd be embarrassed of the answer!
9.5 out of 10 is justified I think. You're right it has technical issues, but I just didn't even care when I was playing it. It's so good I happily forgave all of the little niggles I had with it.
Yeah, I didn't even include the hours I sank into it on the console in my estimate of how much I've played it. I'd probably be at insane amount of hours if I did, lol.
I'm honestly ashamed by how long I've played some games :P
