I'm still slowly working my way through Rogue Trader. It's a lot of fun, but something about it makes me feel satisfied with a session after around an hour in. It's slowing down my progress, but probably the only thing not leading to me burning out and never actually finishing the game.
I am getting an itch to play a gag, so I might pause RT, but I'm also afraid I won't end up coming back to it if I do.
