wouldnt this totaly depend on how the game is actualy built?
i dont play 'shooters' at all, im more of an RPG kinda guy. but its been my experiance that usual a game is set up to favor either gun combat or mele combat, and what ever one it favors, the OTHER one usualy just ends up feeling tacked on.
take vampire Bloodlines as an example. its got mele, its got Guns, in fact that are more guns than anything else in the game. but the game clearly favors mele. even if you WANT to use guns its not a reasonable choice when you can kill a person by just jumping on him and drinking him dry in about 5 seconds, or you can pull out your machine gun and shoot 400 rounds into him , taking 10 minuts to do it just to get him to half health.
on the other hand if you play a shooter, you can duck into cover, set up a sniper shot and have a 1 shot kill, or you can drag out your crow bar, and wale on someone for 10 minuts ......... just to get him to half health.
truly this is a clear case as someone else has said of never bringing a knife to a gun fight. or vice versa.
in fact im interested, can anyone think of a game where BOTH choices are valid in almost any situation? real life says that guns are better than mele weapons in all most every situation. in fact i often scoff at the stupidity some games have of making guns somehow LESS dangerious at close range. (Star wars: knights of the old republic for one) you take a hit in damage if your using a friggen blaster pistol at mele range. well let me tell what, if im getting attacked by a guy with a sword in real life and my choices are either having a sword of my own or having a 9MM. i want the friggen gun at ANY range.
some things this would make sence for, after all its kinda hard to draw a bow and fire an arrow at someone who is swinging a sword at you, but just pointin a gun at them and pulling a trigger isnt.
