I agree, €8 for a cosmetic item is a lot, considering the game cost me €15 or €17—I don't remember exactly. That said, as I mentioned earlier, I don't know how video game development works behind the scenes or what they have to do to fund the project, so I'm fine with it as long as they don't go too far. In fact, I haven’t bought any armor—I’m not the type of player who cares much about how the character looks, I like them but I don't need them.No that is not reasonable.
In every case, the base game is where all the real heavy lifting in creation is done. No addition could ever demand so much work that it would cost nearly the same as the base game. Even at 50% of base game's cost DLC can be considered expensive for nearly every game.
