Hey...I bar no one. I'm just a voice calling from the desert saying "balance, balance!"
I'm a firm believer in balanced game mechanics. When an aspect of a good game goes off kilter because of a bad mechanic, the game moves that much closer to recycle bin. Not saying that will happen to XCOM, but...it did. So many aspects of TFTD moved it to the recycle bin. They took the framework of XCOM and doubled down...but doubled down in some of the wrong areas. Made it incredibly brutal, made it incredibly tedious, doubled down on the need to micromanage even more...and lost it. I was in my late 20s when XCOM came out. Do the math. I remember pulling a copy off the shelf and watching a sales guy grimace at the game while saying to me it was nigh unplayable.
But I do digress. Again...I bar no one. I think its a great idea, just, imo, it would be great to find the sweet spot on the idea. Hell, it would require a code change to do. So its fantasy on top of fantasy at this point...but very doable. Clearly their is criteria for knowing if a weapon is two handed when fired and if a second weapon is present. A simple condition of if both hands have the exact same weapon item, and they are both one handed, allow the option "Akimbo" to display in addition to the firing options. if Akimbo is selected, then do attacks as normal for both weapons, reduced for accuracy. Or simpler even further...if condition is met and Akimbo is selected, double TU cost and fire both weapons per normal with a bonus of % morale damage for each successive hit out of the grouping.
