Disclaimer so I don't get buried, I have not glitched. I was tempted but, fr fear of a reset decided against it. So now on to the topic.
People $$$ in this game affects another player virtually 0%. I have read over the forums and have heard people say, they can buy faster cars in races. Not if Custom Cars are turned off. So their money means 0.
They can use merriweather services, Yes. Each service about once every 15 minutes or so. Besides the airstrike most of it is weak and even the airstrike you have to sneak up on someone to use. The delay is extensive and the strike area is limited.
Clothing is another $$ based thing that has nothing to do with you.
Weapons is another cry, The problem is that you have to get the level to get the weapon and a pistol works better than an assault rifle in certain situations. I have lost to people 20 levels lower than me and beat people several levels above me. Even a 123 yesterday.
The cars are personal prizes that mostly sit in the garage and I think most of the gripe about this is that people want the cars they see on the street. Me I know I will get their soon. Im at 745k right now towards the Adder.
Lastly and this is the biggest reason that money has no bearing on the outcome or the enjoyment of the game is that you can ACTUALLY PURCHASE GTA$ with real money.
So basically you guys are telling me that if someone spend 100$ and got 20Mil and called in an air strike on you that would be better than someone who glitched 20Mil and did the same. R* took care to make sure that it couldn't be that way.
I am one of the people who hate lvl access games. But, I understand why they did it because of the game cash cards. If the cash cards weren't in the game everything would probably be cash and carry instead of rank up.
As for people crying about people farming missions, get over yourselves. If someone has the patience to do the same mission 100-200 times a week more power to them. I would think that's a very boring way to do it.
