No seriously.
Look:
SA:MP has got only deathmatch servers over WHOLE san andreas, or some parts of it! That's too big! Multi Theft Auto must get there chance with there own TDM on a small minimap where you can hide etc.
And now, the big servers at MTA have only those DM over whole san andreas, what is too big. Every player of MTA DM can look to SA:MP and see that it's almost the same and play there.
So the new games like TDM in a minimap, or even CtO, CtV must take there chance.
So I will say to get more people playing MTA DM:
Get more servers. Servers with: TDM in a small map, CtO, Ctv, hay, fallout and those others.
MTA FTW!
