3. Warhammer 40 000: Space Marine
Some might find it odd that the first game on this list from a licensed brand happens to be one that has one of the richest backgrounds of gaming history but Warhammer 40000: Space Marine does its level best to ignore the interesting parts of the universe's writing to pursue what can only be described as a pretty pedestrian plot.Vanilla characters and dialogue that does little to immerse the player in the game are some of the worst of the flaws- particularly when you have Mark Strong doing the best he can to give this game some gravitas it truly lacks. Nothing about the deeper, more interesting influences and thematic philosophies of Warhammer 40000 are even touched upon- this may seem a bit much to ask for, but Vampire the Masqurade: Bloodlines is a good example of a tabletop game actually paying some respect to its material, rather than making something bland, vanilla and inoffensive to as much people as possible. Perhaps this was because THQ was relying heavily on this for sales but if that's the case then surely a bit more effort could have been made to engage with the player? With a twist that can be seen miles away and a group of characters that seem to grow more dull as the game goes on Warhammer 40 000: Space Marine bypasses much which makes Warhammer 40 000 the most popular tabletop wargame.
