I’d still rather have seen Stalingrad entirely locked behind a paywall. Would eliminate any accusation of pay-to-win in that campaign, and wouldn’t feel like a drug dealer giving you the first taste for free.
You are making yourself sad drug addict by your logic.
I can hardly understand why your kind of people feel so offended by the very existence of a price tag. F2P is often harshier than normal games, and one more F2P campaign can cause serious trouble. 3 different F2P campaign for Eastern Front? That’s absurd. They made the right choice.
Just confess that you want a freeware made by volunteers.
