I love the game, it's one of the few horror games I actually have the guts to play, next to Five Nights at Freddy's. If it weren't for this game, I would have never gotten into SCP in the first place.
It looks like a cheap, mediocre horror game with relatively little replay value.
Honestly, it's another Five Nights at Freddy's or Slender.
Keep in mind that both SCP: Containment Breach
and the two other games you mentioned were almost entirely made by one person, so of course it's not gonna be as polished as some other big title games; but that doesn't make it bad, it just means that it needs some work to make it even better. The people who make these kind of games don't exactly have the biggest budget in the world, nor do they have all the time; they have to deal with what they've got and they do a pretty darn good job of doing so.
I must admit that the replayability of Freddy's and Slender is very small, but to say that Containment Breach doesn't have replay value, though... given its randomly generated nature and multiple endings, I'm gonna have to strongly disagree with you on that one. Actually, now I must ask, how much have you seen of this game? Clearly you haven't played it for yourself, and I'm starting to doubt that you even know enough about it to give a valid opinion on it. I mean, come on, you didn't even know how old the game is.
