Played Convoy. The obvious (and acknowledged) comparison is to FTL, from design to art style and even music.
Basic premise is, you are moving an MCV (basically a large truck) through the wasteland, with up to four escourt cars to protect it. The MCV is immobile and starts pretty defenseless, but packs a punch by the end of a run; the escourts can move around to block other cars, shoot at enemies, avoid environmental hazards, etc.
Pros:
-Worldmap, you get to choose where to go and when (which makes it too easy on easy, but that's on me). You can take on quests, choose whether it's time to head back to camp for repairs/fuel or not yet, venture into high security areas or go around them (wasting time and fuel), etc.
-Minibosses!
-You can bump cars, which damages both cars (although the right equipment will turn that damage heavily in your favour), but can also throw them into cliffs for an instakill or what have you (the enemy doesn't bump you, at least not on easy). Positioning is very, very important to block each other and defend your MCV.
-You can choose your MCV, up to four different escourts, and the equipment on all of them. That's a lot of choosing.
Cons:
-You can't escape a fight once you've started it. That's a pretty big deal for a roguelike...
-MCV weapons are fun, but escourt weapons feel very samey. Unlike in FTL, where's there's no mistaking an ion cannon from a laser from a fire bomb. Which leads to late game fights feeling very repetitive.
I think what FTL did best is that fights were very reactive. Nothing ever went according to plan, and you had to make difficult decisions about your priorities if you wanted to survive (what weapon do I power? Do I turn off the oxygen? Who do I send to repair that breach? Do I damage their shield room or their weapon room first? etc). While there's a bit of that in Convoy, it's not often enough, and there is not enough variety in your build IMHO (not like FTL is perfect in that regard, considering that you still need a build that can defeat the flagship, and not all viable builds can).
Anyway, if you want to see another take on FTL, Convoy is pretty fun (Mad Max theme helps), if flawed.
