Well, have you ever shot a tommy gun? It is gonna be all you will want to use. Watch. Plus it fits the vegas mafia style that everyone wants.
I will go ahead & just start off with what you just said, yes that is what everyone wants (most people). The developers wanted to be
different then Fallout 2's New Reno, so instead of mobsters controlling the majority of Vegas it's . . .Cartoon Robots on wheels. Im not saying there should be bouncers holding Tommy Gun's at every entrance to every casino in New Vegas, I am simply saying that while New Vegas is based off things like the movie Casino, Ocean's 11 & the rat pack era etc it is still a video game. Video games are suppose to be fun, the majority would find it more interesting if New Vegas was a bit more like New Reno and most your people who did not like New Reno won't like New Vegas anyway for the fact that it takes away from the setting (Fallout 1 only fan's I am of course refering to). You can still have a very legitimate well ran Howard Hughes corporate style Vegas without having police robots running around on one wheel in your facel taking away from the immersion of New Vegas it self.
Nicky Santoro would have a real hard frickin time pulling half the stuff he pulled in Vegas with up in your face robot police on wheels running around ill tell you that.
PC mods of course fix the up in your face police robot problem, then I guess from the developers stand point most console players are pretty much completey unfamiliar with Fallout 2 and the game is already a step up from Fallout 3 in there view.
I would at least really like to see a professionly done Tommy Gun in New Vegas, I am not a modder and or else id try my hand at making a good Tommy Gun for New Vegas. Obsidian cleary are some gun nutt's, the compact grease gun is cool and sounds pretty legit, so if the Tommy Gun made it in or is DLC I will at least be happy to have that as modding up in your face robot police OUT of New Vegas is most likley not too hard . . . Making a good Tommy Gun mod probably is.
