You can buy good hosting for your RP game. I used to play GTA San Andreas online and loved playing it, but the server I played on had terrible hosting. I was at school, and the only thing I could think about was how I would play the game once I went home. I would go home, and the server was down when I wanted to play the game. It was terrible, but I managed to find a better server later.
Now I have a website, and I have the best hosting available. I found cheap VPS hosting on the time4vps website. It's worth paying for good hosting. I would hate to have any problems with my website.
