Played my first game of 8th today, and probably my first semi-serious game of 40K since... 4th edition? And it was fun! Helps that jus is a cool dude, of course. I made some blunders and ended up losing, but I was in the game until the death guard terminator lord wiped out my own terminator squad. I was pleasantly surprised to find that power level 50 / 1000 points gave a really fun game, along with being the "supported platoon" level that (I feel) works pretty well for 28mm minis on a 6x4 table.
40K is fun, would play again, will try to exercise willpower enough to not buy anything new until I paint the primaris stuff I'm getting from MiJ next month.
Note for Jus - the Blight Launcher on the dude from the First Strike box is 24" range, Assault 2, S 6, Sv -2, D3 wounds, and you can reroll 1's to damage. Scary stuff.
