So we've all been there. Maybe with Shadowrun, maybe with some other game. Regardless of circumstance, you've been playing for a while, but you've got to leave the game. Maybe you don't like how the DM runs it. Maybe they don't want you there. Maybe RL intervenes. Maybe something else happens entirely. The whys and wherefores don't matter for this discussion. Long and the short is, you're leaving the game, and it is probably likely you won't be gaming with that DM/group again.
Now, we've all been tempted to give them a double dose of the one-finger salute, include a few comments about their intelligence/body stature/parentage/hygiene, and in general make them feel like they just got out of a comedy show where they made the mistake of annoying the comedian, who then filled the rest of their five minutes with nothing but you. But let's be honest, that isn't the best way to do things, is it? So in line with the 'what would you tell a new player' threads, what are your tips for making the graceful exit from the game. Keep it classy, now.
