Now, I like all of them, and they are good friends, but I does get tiring to play with two of them. One doesn't care at all about parts that don't involve him, and distracts other players and just makes the whole thing lose its focus. Any complaint about that he disregards as him "wanting to hangout with friends and not just play". Doesn't help that he has zero commitment. The other is a good RP-er, but has ridiculous amount of trouble with the rules. Just last week, after over 5 years playing 3.5/PF, he asked me with a straight face what "Fort Ref and Will Save" on the class table meant. You can't make this stuff up. More stuff about him
in this old thread.
Additionally, I feel like everyone steps on each other's toes mechanics wise. Nobody is super unique in skill/gear selection, so people always fight for the spotlight. Roles aren't clearly defined, the Ninja has higher stealth and disable device than me, but can't scout because he lacks trapfinding. Three people have diplomacy maxxed out, so social situations you have all of them arguing different points and it's a mess. So on.
Lastly, it makes scheduling games a freaking nightmare. Last night our session lasted a whole two hours because the guy that's only interested in his moments was too tired to play. No other days available this week or the next. The one after that is gonna be tough as well. We'll be lucky to play at all in November.
