I read somewhere that Wesnoth was in parts inspired by sega genesis game Warsong, but i see that not in one important part trough, or players would not feel so unlucky and get into situations where they want to abuse save/load mechanics to get a better luck. In Wesnoth each unit accumulates experience and they get more and more valuable and irreplaceable later in the game campaigns. In Warsong commander units each have up to 8 hired units under their command and get experience from hired units fights, while hired units do not accumulate experience at all, being cannon fodder. Before players would lose valuable commander to luck they would lose 8 unvaluable troops in a row at which point it is impossible to blame luck. Players always feel in control of the battle even through fight outcomes are very random.
