After the demise of WHFB, some of my clubmates have been looking at alternatives.
Had a game of Osprey's Dragon Rampant last night. https://ospreypublishing.com/dragon-rampant
64 pages means it's pretty easy to pick up & play. Each player has 6-12 units, with 6-12 "Wounds" each. Man-sized models have 1-2 wounds, monster types (Including wizards!) have up to 6.
Rather than the IGO-UGO system, it works on initiative rolls to activate a unit, each unit can be activated once per turn, rally, move (Including charge & fight), shoot (including spells).
If you fail your activation roll, then that's end of your turn & your oppo gets to go! Means you have to think hard what unit to activate in which order.
Terrain can be a great equaliser, a weedy unit sat in a wood etc (Difficult terrain), fights hand to hand as well as a burly unit of Knights, who'd otherwise trample them into the ground.
You can choose from several scenarios & get extra points from achieving certain objectives (& lose points if you fail to achieve them).
For £11.99, it's more than worth getting & use those models sat in their lonely case again!
