People aren't not playing this game because their ping is bad lol. People don't play this game because it's old and there's better things to play?? Unfortunately is how it is. Creating more game worlds has been suggested so many times at this point we've lost count and it's always the same logical answer to this question/suggestion, why would we want to spread an already small playerbase out across multiple game worlds? It makes 0 sense unfortunately

PS: The most important thing for playing RSC is to have a STABLE connection. You could live in Australia with 500 ping, as long as you're on a stable (wired/ethernet) connection you're fine. Example, open CMD (windows), type ping rscrevolution.com and you should be seeing a minimum / maximum / average ping reading of roughly the same number. IF your results are all over the place it means your connection is unstable therefore you will lag. Typically 4g / hotspots / connecting to internet via wifi and all create issues. For example, typically in my hometown in the UK on fast fibre connection my min/max/average ping is 40. Just 1 hour away from there at my other property (rural area), connected via wifi to a 4g antenna, my ping is more like 150 but frequently jumps to 250-300++ which creates horrendous lag spikes in game.

TLDR; get a stable connection
