After the Alphas will come Betas, and after the betas will come the final release. All of part one Part one is the part we're working on at the moment, including the civs which were important during the 500BC to 1BC time period, and including the basic RTS gameplay. After we've finished part one (through alphas, betas and through to the final release) the idea is to continue to add the civs which were important during the 1AD to 500AD time period and expand on the gameplay. It remains to be seen exactly how work continues after part one is done, whether we split it up in smaller batches (part 1.1, part 1.2, etc) or do something similar to now with alphas, betas and eventually a final release of all the new content.
