Hello welcome. If you are new don't worry about anything being too complicated. Designed with the purpose of making players hardly even familiar with little wargame. Never played sc2? not a problem either. There are 3 sc2 factions and 1 custom race. There's plenty of differences as it is not StarCraft nor lwg but that aside most of it is rather simple and balanced as can be.
1/3rd sc2 1/3rd Little War Game 1/3rd its own game. Features like sc2 endless cross dynamics combat situations of air, stealth, upgrades, aoe, transports, light harrassment units, % based damage dealers ect.
