Lemmings was one of the 3-5 inspirations for the Commandos games: - giving different tasks to characters over the level to finish it. Lost Vikings won over Cannonfodder and the Commandos would be very defined characters not a mass of generic soldiers. - levels structured as "bubbles" of logical challenge; after you solve one you typically move on to the next one, eventually reaching the level finish.
The Commandos series also parallels a bit of the history, fizzling out very quickly after Commandos 2, when it might have seemed that the sky was the limit for the series.
