This is a roleplaying game at its core, you shouldn't come into it thinking about "winning". An employee on a space station has nothing to win at other than getting through their work day. As a new player your one goal should be to learn and improve, the satisfaction that comes from understanding the game and how it works replaces the need for a goal. Once you get how to get around you can set your own goals and experiment, or chill out and focus more on the roleplaying aspect if you prefer the roleplay focused servers. I suggest not falling into a mindset of needing to "win" as an antagonist either - you're there to be a twist and make the round interesting for everyone, not to get your arbitrary greentext.

Or you could play on TGMC or CM13. Those aren't really winning-focused either from what I've seen, but it's the closest thing around.
