I quite enjoyed my time with Convoy. You are onboard a large interstellar ship that goes down on a foreign planet. Your ship needs repairs and you are the man to go out into the world and get the parts your ship needs.
That is the setup for you to pilot your convoy through the wilderness in search of parts, scrap, tactical combat, new weapons and vehicles, and unique encounters. There is a constant risk/reward balance that these types of games usually need to be compelling. Do you buy that new weapon or stock up on fuel? Do you try and supercharge your engines to escape this upcoming combat encounter, using extra fuel, because you're banged up from the last encounter? What choice do you make in this random encounter scenario?
The game reminds me in many ways of FTL, except instead of controlling a single static ship you are controlling several vehicles which can move. That adds a layer of tactical combat that is quite rewarding. Now things like range, speed, maneuverability and terrain matter, not just the stats of your vehicles or what equipment you have. There's nothing quite as rewarding as ramming your opponent into a wall or buzzsawing them to death.
There is a definite "Mad Max" vibe to this world and the graphics, while simple, reinforce this. My biggest complaint is that is feels a bit light on content compared to other roguelite type games.
Bottom line, if the idea of driving across the wastes of a forbidding planet battling pirates and scrounging parts sounds fun to you, and it is fun for me, then buy this game.
