Here are some of my ideas. I would like to hear everyone else as well.
1. Steam sale - $40 is a lot for many people, especially this being a per-release. The only reason I bought the game when I did is because my wife surprised me with a Steam card. Thats not to say I dont love it at all, because I do. However, I was going to have to wait a while until I bought this game.
2. Clan Support - I think clans are a great way to keep up a multiplayer environment. For example, my clan, The Art of Warfare (TAW) is a large crutch for Hawken's ability to maintain a competitive circuit, and that's because clans provide an environment where people are surrounded by the games they love, with people who love them as well. I think embracing clans as part of the multiplayer system, a la StarCraft 2, LoL, DoTA, etc., will enhance the gameplay for those wanting to get deeper into the game.
3. Ladder/Matchmaking - Though I'm sure this has been discussed, ladder is a great way to keep people into a game, as they want to keep progressing among their peers.
4. This may be a more personal one, but giving the races/factions their own identity. One of the things that I love about StarCraft, is that your race defines your playstyle, and maybe, even your own personality. For me, I loved feeling represented by protoss. There was a certain pride I felt whenever my race would win competitions and such. Maybe having something like that in OTC could help grow the community in a way that takes pride in being robotic or scientific or what not, thus making us want to explore our factions even more which would help lead to the establishments of different builds/metas/strats/etc.
Anyway, these are things that I have noticed which might help the game. I am by no means a game developer of anykind, simply a lover of video games. To be honest, I want this game to be my new StarCraft. I am growing tired of the boring RTS style of roll a dice, pick a build, or whatever. This game is a breath of fresh air to the RTS genre, and even online gaming as a whole. I hope you all at Mohawk games continue to do amazing and thank you for sharing OTC with us.
P.S. If anyone is looking for a clan to join, I am currently working on getting a OTC division spun up in TAW. For more info on TAW, feel free to message me, or visit our website at www.taw.net
