It appears that you carry a completely different definition of roleplaying than I do. To me, Roleplaying involves using decription of actions to either improve odds or to replace the need for a roll. The other is in conversation to advance a story arc.
The type of Roleplaying I despise is stalling an important action that can say "save everyone on the ship". Roleplay has it's place, But the situation must be taken into account. I find it rather annoying when I can not take an action that can benefit the party over the fact that certain roleplaying styles and myself come to loggerheads.
I hope that this has clairified a few things. I think in an analitical mannerism. Each action or in character creation, is bent toward a purpose. It don't tend to bother with deep character backgrounds, It is what is done with the stat block that defines it.
