Alright. I've had the base CO1 game for a while, never bought any of the expansions for some reason or another, but I'm glad you left Matrix/Slitherine, I am not a fan of them at all.
Going forward, I like what I see in terms of what you are doing with CO2, and I'm ready to buy this initial super pack for $50, no problem at all.
However, what I definitely do not like, is this idea of paying for upgrades to already owned modules. Battlefront has really been getting into this sort of thing lately, and they are quickly turning into one of my most hated dev/publishers just because of that silly system. Among other problems with their Combat Mission series, that is easily one of the silliest, and I would very prefer not to see that here as well. I'm all for paying for new modules, and free engine upgrades are nice. However you can't really say they're free engine upgrades, if the only way you can play on that new engine is to pay to update your modules as well.
Ignoring the initial sale, you are charging 50$ for a currently unknown amount of features to be usable for the modules that you own. Two modules would be 60$ with your pricing system as well. Do you mean to say that these new features are the equivalent content worth of almost two whole modules then? If this game will ever have any form of multiplayer, this is going to be a massive split audience, because not only do you have to pay attention to who has what modules, but also what engine version everyone is on then? Maybe people without certain modules can play along with a player who has more as long as they have the matching modules for the scenario they decide to play, but they both need to be on the same version. Paying for upgrades to something you have already purchased is definitely not going to expand your audience at all either. I know a lot of people who might be interested in this type of game, and they wouldn't buy from matrix to begin with because of the prices, and nothing ever going on sale. They'd look at this model and not even begin to think about saying yes.
I'm very skeptical of this. You look at the mess that is combat mission, and having 7 completely seperate games all running expansions of their own, and now you gotta pay to upgrade each seperate one, and now there's vehicle packs coming out and it's just a mess. All I see in that is money grubbing. I'm glad you guys were good enough to put everything on a single base engine, and make everything modular, but if these engine upgrades are anything like battlefront's where they add a few small things, half of those things not even being recognizable in gameplay, and then charging money for that, I don't see myself buying anything further than the base pack.
Also what about future modules? Are those going to require certain engine versions to run? Because then you're not buying modules at 30$ per, you're buying them at $55-$80 per depending on how many modules you buy and are forced to upgrade the engine and pay for the other module updates.
Also you're charging what seems to be a flat $50 for module updates. What if someone only owns one modules. They should be paying as much to update their module, and people who update the 10-15 modules they own down the road, pay the same? That doesn't seem right either.
I'm not sure how I feel about this at all.
