Bohemia you are standing on what could be a huge multi-player phenomenon. Your game has the potential to be the number one online wargame that could easily rival anything from Call of Duty or Medal of Honor.
In order for this to happen the very first priority for you is to stop creating campaigns and above all (and I mean this is the most loving way possible) stop trying to write stories. You suck at writing stories and dialogue. Your engine is so powerful and offers such a huge amount for so many people but it's weakest element is in story driven campaigns simply because it is so buggy... and this negative experience is compounded by your UTTERLY HORRIBLE WRITING! Please stop, it's getting painful to see.
When you have come to terms with this and you are ready to move on it is time for you to move everything you have over to multiplayer development. Go nuts, experiment, sort out your netcode... really push this engine to the limits in terms of optimization and streamlining the combat experience. I don't mean simplify but rather lubricate ;).
I am not suggesting I am TELLING you that if you focus on multiplayer and you really polish it up to a blinding sheen, still offering the highly complex, customisable multiplayer experience with the ease of access that Battlefield or Call of Duty offers with smooth online combat in a large scale environment for PVP or PVE you WILL see your bank balance begin to bulge at the seems.
Or you can continue to pump out these lacklustre, bug ridden, terribly written campaigns that nobody truly cares about, wasting your time and wasting a potentially wonderful opportunity.
Just imagine if you were to divert your entire team of talented and skilled individuals into creating a planetside type shooter MMO based on ArmAII. Imagine if it were easy to access, smooth to play and offering the kind of scale and scope most FPS shooters players simply couldn't imagine. Imagine if you charged a reasonable price for a subscription; say £3-4 per month.
You are talking about a piece of demographic pie that has been left on the windowsill with not so much as a sniff from anyone else out there. If you grabbed that pie with both hands you are looking at potentially millions of players over a very short period of time all clambering over each other to play your game.
Think about it Bohemia... you are missing a real opportunity here. In case you think I am some fool who doesn't know what he is talking about I humbly inform you that I work for an internationally acclaimed MMO that boasts just over a million players... I understand the market, the medium and I understand your game, being a dedicated Opflash/ Arma fan since 2001.
Nobody understands what we are looking for better than you. Do it... DO IT!... before someone else does.
