Started Mech Armada, a roguelite which is turn based and with a fairly good customisation system which gives full freedom in making units from what you ‘find’ (pay to unlock randomly by paying a resource which is also used for other things so you have to choose) in the run.

Required a fair bit of learning through experimentation but now I, at least keep winning the first map and have just reached the boss of the second. Without any of the ‘roguelite’ bonuses. Which you can unlock with a separate currency earned. I chose not to unlock anything to see how viable it is without unlocks. It is decent. That said, there are more pieces added to the ‘gacha’ as you play. Through an experience system. The experience system carries over between runs but is not really a ‘boost’ since it just unlocks a bigger pool of more varied parts.
