I tried it once, and now I'm going to try it again!
A simple enough RP premise; a small (5-6) Marine squad of Primaris Intercessors (of the Unnumbered Sons, unless anyone can tell me there's mixed lineage Chapters for Primaris somewhere?) doing what Astartes do after the almost complete collapse of the galaxy - may possibly go down a Deathwatch route, that'd make more sense for multiple gene-lines, but we shall see if anyone's interested first.
So, anyone interested for some linearly paced and set essentially bolter porn? I won't be asking for Character Sheets, only a decent level of English and a willingness to purge for the Man-Emperor. If you reckon Deathwatch would be the way to go, and/or have any questions, feel free to say/ask.
The Emperor protects.
