So my current group, with me as the Imperial player, has pretty much fallen off the wheels (which, unfortunately, appears to be a common occurrence with this game). We are 5 missions in with a tally of 4 Imperial victories and 1 Rebel victory. One player now refuses to play anymore because they think that the game is broken and unbalanced in favor of the Imperial player. Prior to starting IA, this same group of players and I completed a Descent 2E campaign, again with me playing the role of the Overlord. Similar sentiments came up from this same player during that campaign as well after they lost a couple of scenarios, but they ultimately won that campaign. However, I pretty much ran the final two scenarios on super easy mode for the heroes in order to avoid any further strife (i.e., I didn't reinforce monster groups when I could and didn't implement some of the rules that added additional challenges). I have thought about doing the same for the current IA campaign, but there isn't much more I can do to "dumb" it down before it just become un-fun for everyone (including me). Plus, doing so ultimately defeats the purpose of even playing to begin with. If I allowed the heroes to win every mission every time, then we would just keep playing the same campaign missions over and over again during every play though of a campaign. I keep trying to tell the rebel players that they should look at a loss as an opportunity to experience the game a different way the next time, but they just don't see that. Most of the missions have come down to very narrow victories for the Empire, and if the rebels played the same mission again, they would probably win the second and subsequent times though. I have GM'ed plenty of Star Wars RPG sessions, but I just don't see this as a sort of game where the Imperial player should play like a GM...it's meant to be a challenge for ALL players with loss being a perfectly acceptable outcome. Plus, the Rebels could loose EVERY mission other than the final one and still win the campaign. However, the one player doesn't see it this way and just thinks the game is overall un-fun (which was not their final opinion of Descent 2E).
Anyway....what do the rest of you do in this situation and is there any way to salvage it (apart from just replacing the dissatisfied player with someone else)?
