Hey guys. You see I have all the Sins of solar empire. Original, Entrenchment, and Diplomacy. I understand some don't have the expansions but which one has more people playing? Im a noob at Sins. I only played one online match cause I suck and its so hard to find just one match online.
Like the guys said, most of the action, at least the PvP action, is on the Diplomacy expansion where you can find 3v3s, 4v4s, and 5v5s. Sadly, this two-and-a-half year old game just has low player counts now. The release of Starcraft 2 really hurt. Things were pretty decent in Entrenchment, but the release of the Diplomacy expansion also hurt the player counts for reasons I don't fully understand. (Perhaps no one wanted to spend another $10 on a game that never had high player counts to begin with.) Also, this game just never had high online player counts. The most people I ever saw online at once was about 280 people about two months after the game's release. Sins also suffered from numerous technical problems at the beginning (which have mostly been fixed) such as minidumps, desyncs, and huge game hosting problems. I think some people also don't like Impulse and never updated the game, which cost us more players. It's a shame because Sins is an amazing game that deserves to have more people online.
The best time to play seems to be Sunday late afternoon and into the evening, North American time. As a general rule, the North American evening is the best time. There are normally a couple 4v4s and 5v5s each night on Diplomacy, but you have to patiently wait for them.
Also, expect to get totally thumped as a new player because this game has a learning curve. You should play it for at least a month in single player until you feel comfortable with all of the game mechanics and have a knowledge of each race's ships, starbases, abilities, tech trees, strengths, and weaknesses. Then you'll be ready to start playing against other people as an entry-level player. When you join a large game, it's a good idea to point out that you are new and not a smurf but have played it heavily in single player for weeks and know the basics.
I also think you are better off choosing your colonizer capital ship (mothership) as your first capital ship. At the start of a game, order it up immediately, scout and then use it to take your asteroid. Also, don't build more than 2 caps and keep them out of combat because more experienced players will focus fire them to death and they'll die for nothing. As a new player, your goal is to just survive and be as big of a pain-in-the-ass as possible--as large of an annoying speed bump as you can to your opponent. Your goal is to keep a mothership or two alive so that you can always colonize something later on and to buy time for the more experienced players on your team to win their fights.
If you start out in a safe "eco" slot with allies on both flanks, then your job is to build up an economy as quickly as you can and start feeding credits and resources to your allies. (You have to research the feed ability in Diplomacy.) If you start out in the "suicide" spot with opponents on either flank, then you just try to survive the best you can and send one Mothership to the middle of the map to colonize stuff.
