Recently, I decided to relive my younger days and install Call of Duty: Mobile. I used to play shooters on PC, but the mobile version really surprised me — the graphics, dynamics, and overall battle feel are almost the same. However, at first, it was hard to keep up without upgrades and new weapons. That’s when I started wondering whether it’s worth spending money in the game or if it’s possible to earn everything honestly. I wanted to understand how realistic that is and whether the fun of the game fades once you start investing in it.
