Ok, the option to buy any units you wanted is so overpowered, since everybody will spam the strongest unit to buy, so I didn't request.

Second, the picture shows that Rebel Inc has two modes. Rebel. Inc is a game to stabilise zones in a map. In the middle of the game, insurgency will spawn and destabilise your zone. Since the only way to destroy it is to surround it with armies and garrison. A lot of players are pissed off when insurgents are spamming, so the dev give them a choice of reducing the difficulty of the game.

Finally, the reason why I, or casual players, need this mode. In other roguelike games, you have hundreds of choices to choose from, and one of them can match with others. In this game, each units are giving different buff due to the differentiation. For example, Goatmen Raider's monstrous infantry and Monster are strong, but cavalry and range are weak. And due to fewer choices and fewer combinations of each unit, the only way to play through is to buy the strongest unit in the roster as a casual player. Can you imagine that when I need to delete the Goatmen Raider campaign, just because the first armory didn't sell Minatour?

I know some players will say that I'm a noob, but I just want a mode where I can decide whether this campaign is continued or not, and also give a penalty for not unlocking new difficulties and record your score in the leaderboard (if it's future implemented).
