[Suggestion] Don't make open.mp a "custom engine that you can mod"

[Codeah]

?-Don't add the ability to remove HUD
[i]?-Don't add custom vehicles. At least, not fully.
?-Don't make custom skins[/i]

I can agree with the custom vehicles point you made. Good vehicle models are hard to make, thus you'll mostly find the "SUPER-FULL-HD BMWS', MERCEDESS' AND AUDIS" which I assume are just ripped off vehicle models from other games.

I can agree with only being able to change skin textures. This would ensure that the game still looks like GTA:SA. And then on top of that it'd be nice if you could apply decals to those textures during run-time. That way you could have tattoos, custom clothing.

However I disagree with the HUD point. In some situation the default HUD can be very annoying and would be better off hidden. Let's say I'm creating a mini-game for my server where I want a completely different HUD. It would be nice to have that option.
I can see the issue here though, some server owners might disable the HUD indefinitely and replace it with their own, I wouldn't like that either. (It depends on the game-mode though)

Server owners shouldn't be given too much power. I wasn't able to find any good MTA servers to play on just because of that, but it wouldn't hurt giving them a bit more power.
