Problem 1: Marketing. RO never got the proper exposure or the community would have easily been twice the size. TWI got screwed badly by their publisher. End of story.
Problem 2: Players are feeble-minded puds. For the most part, players have minimal attention spans and want the newest toy asap. The CoD/MoH type games cater to the larger audience because those games are mostly twitch shooters with immediate gratification. The general playing public is nothing more than ADHD kiddies who are more worried about their kill streak and personal penial enhancement than anything else.
Problem 3: Slow development of custom content. The UT engine is by far, the most complex engine in the genre. Developing vehicles for instance, is a four to six month process PER vehicle. It worsens when you have to cooperate with guys spread all over the place who may be on other teams as well.
Problem 4 (Personal): Mods. All the better in the big picture. Remember how RO got it's start. But, I think going outside the main game is a detriment to the overall community. It serves to fragment what is typically a shrinking community once the long development time of the mods reaches release. Look at games that are non-Steam "everyone plays version X": CoD 1.0 moves to 1.1, community splits. CoD-UO releases, community splits, etc. Personally, I think it is great that the mod teams are doing such large projects and creating new gaming choices, but the two teams that I think will do the most for "Red Orchestra" itself, are CC and our mini-mod team at MinionWorkz because we are adding content to the base game itself.
So, as not to step on DH and MN toes. I applaud you guys for all your hard work and sticking to your vision. That is what custom development is all about. What will happen though, in the end, is that there will be two or three main player bases with some guys crossing over from mod to mod to retail game. It is just how it happens. There will be two or three smaller player bases. And, afterall, the game is soon going to be looking at the end of it's second full year. That's quite an accomplishment. Players tire of the same game in essence, look for other quick fixes, and reasons to upgrade or build new PCs.
TWI has done an outstanding job of supporting this game. Maybe not to the expectations of some but what has been done for this community far outweights anything EA or IW ever did for their WW2 franchises, combined.
