Frankly, from my experience of the game, buggy weapons seem like a bad fit for this game.
- I played at higher difficulty and for this game RNG means death. You NEED to reliably be sure that the mech that will / has moved into shooting position next turn dies, because most of everything basically one-shots you. If you can't be sure that it's dead, it's %buggy chance% of game over.
- refitting mechs is already one of the down-points of this game due to the multiplicative bonus to systems and / or random loot, with parts that go on every mech or so. I like the "battle" part, but the endless refits were getting on my nerves. More weapons = even more complex refits. It'll become "excel : weapon simulator".
What this game might need as an extension is other "player mechs", new "enemy mechs", new pilots, alternate "super mechs" (forgot the name) other game modes with other mechanics (flooding, expanding radiations, capture the flag...), more "biomes" (fighting in zoos, parks, roads...), easier refits (via changing the UI).
