Played Sins vanilla way back and decided to pick Rebellion up during the steam sale.
I really like the game and I wanted to provide some feedback on the multiplayer aspect for a noob viewpoint in case the devs care to improve the experience.
1 - Multiplayer tutorials - would really help highlight key points to a noob going into MP, which as we know is very different to solo play. Stuff like the "eco" role needs to be explained somewhere, it makes sense once u think about it but truly new players would not just automatically know this. It would also help to have a pre-requisite training mission where you are introduced to pointers that are key to the beginning play... e.g. what capital is usually most useful, your role on the team depending on start position, the best first few ships and techs so that you aren't gimped going into mid game. I know this is not easy, but right now there is nothing.
2 - Matchmaking - I have been booted for not having high enuff played ratio (which is fair enuff because the folks in the game want a good expert game) - but it's not right to have someone wait for twenty minutes or more for your game to fill up then kick you. There should be a noob queue system so that folks that don't mind playing with other noobs, just press a button and get auto queued. Auto queued would also get around the other issue I saw where a host wants to stack experienced players on his side and just stomp the noobs. Both these situations lead to the new player not having much fun or even learning much = not queuing again = less peeps playing multiplayer.
I really like Sins but i think the multiplayer experience for a noob really holds it back in terms of player numbers. I think the depth of strategy is so much better than SC2 but SC2's matchmaking system is amazing. What I am talking about above is not because I dont like to learn.. i do, but the MP system currently strongly favors experienced players and discourages new players. That is fine if that is the only crowd this game is for, i'm not sure if that is the case but i thought I would share my experience.
