I ran Age of Rebellion for a year and a half and that whole experience managed to turn me from thinking the narrative dice system was kind of neat into sort of hating it. It led to a lot of petty arguments at my table and I found it frankly unfun to GM after a time. I love Star Wars more than most people love their families, so I toughed it out for a while but at this point if I run a Star Wars game again I'll probably go back to Saga or WEG's d6. Whereas Roll and Keep has its issues, but I've also been running a game of L5R basically constantly for the better half of a decade now and am more fond of the system than I am any other I've played.
I really, really, really hope it isn't Genesys run (or has rules for both? Except last time we had a split ruleset we had L5R 2e which was garbage), but don't have too much hope. All the nu5R setting lore being in one nice consolidated spot will be useful if I ever want to run a game set outside of the weird canon my gametable has developed over the years as our own divergence from the AEG canon though.
I'm trying not to sound like I'm ******** hard over FFG here, I have really enjoyed what I've seen of the LCG and had a great time over the years with their 40k games which ran on a d100 system. I just am not a fan of the Genesys engine in the experiences I've had.
