I purchased TalonsSoft's East Front, East Front II, than JTCS East Front II...
another game to buy, East Front III, or there will be a different business model ?
Ha. I missed TalonSoft's East Front, got in with West Front a year later. I then duly bought East Front II. Those kept me happy for a while, as there were scenarios available at Scenario Depot etc at the time. For the grande TalonSoft finale, I bought their TalonSoft Campaign Series Gold game pack, with WF and EFII again, but with Rising Sun and all the Scenario CDs too.
Then, of course, I bought the Matrix JTCS bundle too. So that's buying the East Front three times as well, same to you
"East Front III" will likely be the "Campaign Series: East Front 1939 - 1941" base game. You can expect pretty much the same amount of scenarios at day one as with CS:ME, so eightyish or thereabouts. CS:EF 1939-1941 will then be followed by DLC add-ons to add the remaining years, maybe as two DLCs, two years each. Maybe. Too early to have details on this yet. But that's the idea.
Ditto for West Front and Pacific Front.
This way we can have them available sooner, instead of creating something similar to the Matrix JTCS bundle, which includes all the TalonSoft work from the years they produced the CS series.
Similarly, the plan is CS: Vietnam will have additional DLCs as well, to add historical and perhaps what-if conflicts of the region to the base game.
All the while, the new Campaign Series game engine will evolve, and will be available to each previous base game as new ones come aboard.
So even if there's players who are not interested in anything but Middle East conflicts, the CSME experience will continue to be enhanced.
This, all, is the plan at least. As it stands. You never know what Real Life introduces, as we are part timers for most part.
But so far so good!
