I put 55 hours into Star Conflict, a similar PVE/PVP F2P game from Gaijin. I only put 3 hours into this before seeing the same structure, which is unbearable PVE in early levels, and then impossible PVP when other players are paying for vehicles and parts.

Except in this case, Crossout is pretty boring. You can drive around a desert with uninteresting landmarks, brown colour schemes and nothing but enemies or mission markers around. Even with the vehicle-building aspect, there's no hook or anything to pull the player in, except a sunk-cost fallacy if you ended up purchasing something for this game. Even if you paid to win, I don't see how showing up to the same arena to dunk on bots and noobs would be exciting.

I'd recommend something like Mechwarrior Online instead. Even though you can't build a vehicle from the frame upwards, there is interesting customization attached to lore, strategy, tactics, great gunplay, and actually populated servers for matches.
