the poker night duology is an interesting one, because in retrospect, after having playing both, I think 1 holds up better than 2 does for two specific reasons.
1: the items in tf2 are so much better than 2's it's insane
2: you can make the characters shut the fuck up as well as skip their dialog, which unless I'm stupid is straight up missing from the sequel. why? idk.
my first reason is pretty subjective, but the second one is so important for long term play. 2 feels so much clunkier once the charm wears off and you start hearing the same 10 conversations over and over. either way, poker night 1 is just poker with video game characters. most people only care about this nowadays for the tf2 stuff, and its really damn good. a totally ok poker sim, nothing I'll dedicate much time to
