Yes. A lot of games are getting greedy with it too. The costs of microtransactions are skyrocketing. It's insane.
I started playing Star Trek Fleet Command on my phone and it's actually a really well put together game. The issue being... everything is designed to make you pay. Forced PvP, and you can buy the things that make your ships stronger. One ship can't even be earned for free, you have to buy it... and it is over 3x the strength of other ships of the same level. Eventually, your upgrades start requiring refined resources, and you have to manually mine the unrefined resources. This takes hours, and you can be attacked while mining. Your ship gets destroyed, you have to repair it (which costs resources and time) and you lose the mining spot. Well, that's annoying, but wait, there's more! You also lose the majority of the resources you've mined. Spent the last 6 hours mining 12000 crystal? Congrats, you get to keep 350 of that. The cheapest refinement costs 3000 minerals, and you get ~100 refined minerals from it. You can do this once every ten hours. The cheapest upgrade costs over 300 refined minerals.
The game would be amazing if it weren't designed to milk you dry.
You can skip the timers and such by simply buying the resources you need with latinum. 300 refined minerals is something like 75 latinum... which costs over $10. Before I uninstalled the game, the "sales" offered to me were all over $60. Two packs were over $130. And you only get marginal return from this. Maybe a million parsteel, which you use for building, and at that point each building upgrade costs 60k+ parsteel. You get some research points, again, not that much. Some resources, again, not that much. Recruit tokens, which are like lootboxes. You get maybe five boxes worth of recruits, which get you cards, which get you the chance to unlock officers for your ships. All randomized. All for the affordable and very fair price of a quarter of your rent. For some pixels that don't even dramatically change your gameplay experience.
It's really frustrating, actually. If it were simply a money grab it'd be easy to ignore. But the developers actually made a good game. Allow for PvE, remove the paywalls, and you've got a game that will give you at least a month of entertainment. 40+ hours, easily. And I would be glad to support a developer who does that. I'm not opposed to buying microtransactions. But c'mon. They built something good and then went in with a studied hand to add obstacles to your enjoyment, all designed to pressure you into paying them money. And the money they pressure you to pay is just an astronomical amount. It's garbage and unethical.
