it always irked me on a new account when I couldn’t comment in a subreddit because I didn’t have enough comment karma. How am I supposed to get it if I’m not allowed to comment.

why do people care about karma so much tho?

I was a bit confused when you said local co-op. It implies 2 computers on the same local network(connected to the same router, no internet connection required). I think the term you’re looking for is split screen gaming.

When I looked at pictures of Spelunky games like Clonk and Liero popped into mind, I think there are options for split screen multiplayer in those games, they’re old school PvP games.
