I think 5 Core does a fantastic job of recreating the tension of small modern skirmishes without a lot of rules. The guts of the main rulebook being only a couple dozen pages.
This killing machine dropped 3 enemies in 3 shots.
The rules could easily be called "roll and look for 1s & 6s, because that's all that really matters". Before each player turn, a player rolls a die and if a 1 or 6 shows up something special happens, "Scurry" or "Firefight". If this doesn't happen, then a player can activate 2 members of their unit.I really, really love how cover works. No screwing around with how much the model is showing or line of sight. It is assumed every model is trying his best to not get shot, so unless he actively "peeks" around a corner or out of cover he cannot be shot. Period.
Short range weapons (pistols, SMGs) only shoot 12", everything else is in range. Roll one color die for KIll, another color for Shock. Look for 1s or 6s.
Sounds easy, but the tactics are where this game shines.
Throw in the Five Parsecs from Home SciFi expansion with its really slick campaign/RPG system and I am sold.
I used OLD SCHOOL WH40K for this skirmish, but 15mm SciFi I think is the way to go. It might get me to by a few WW2 miniatures again for some commando raids...
