Why wouldn't you? Are you one of those people who can only watch a movie once? New Reno, as any good movie, should be experienced more than once. So why not add New Reno into a modern game.
I can watch movies again every now and then but theres a diffrence between an old movie and a pointless remake.
Just seems kinda pointless going back to reno when got similer themes going in vegas(albit needed to be expanded abit more) and what would be the main plot of going back to Reno.
Area 51 is that sort of cliched area where could end up an alien DLC , you say aliens dont need to be in but given Area 51(from another thread) is known for UFOs and that was big in the 50s it would be a big part of the DLC if it was made. Best let more original ideas take place like big empty to lonesome road then the cliches of Area 51
