Wesnoth is horrible. The authors pridefully state they follow the KISS rule, as if making simplistic games was an achievement. Worse still, Wesnoth is (or tries to be) a strategy game. Result? Shit. Highlights include: one unit per hex; casters and ranged units having same range as melee units; support units not getting XP for actually supporting; broken XP system requiring lots of micromanagement of who gets the last blow; turn limits; combat system in which only thing that matters is terrain your unit is on; HP of units not having any impact on their combat abilities; unlimited counters; the previous three together, which means you might literally lose your entire army attacking one well positioned enemy unit.
