I simply can’t believe that they released the game in this unfinished state. Early access or a public beta would be understandable, but you just don’t release a half-finished product promising to deliver the remaining stuff later.
The Minecraft way where you continually provide upgrades for your game can obviously work, but in that case, the game is cheaper and the upgrades are free. If they were going that route, CS2 should have been a free upgrade of CS1 with all the features of the previous product and nobody would’ve complained.
If you buy another full product, you expect another full product.
USB devices are also hotpluggable, but that doesn’t mean that the data stays in the system if you just pull out the HDD.
