It would be really cool to see, instead of standard Difficulty of "Normal, Hard" to have an Advanced Gameplay Options menu that adds difficulty/randomness to the game itself. At least this is what I would like to see for the series as it goes forward, in patches or a 'final' edition.
Here's the XCOM example:
Some ideas for completely optional things to select:
- Iron Man
- Bronze Man (secondary add-on for Iron Man, can restart mission only)
- Stock Only
- (TACs) Through Armor Critical Chance
- Table Top Indirect Fire (one unit must sacrifice its turn to "Spot" first)
- Engine Explosions (chance engine will explode, causing nearby damage)
- Pilot Damage Random (determined by skill check levels, may or may not take damage by chance)
- Multi-Target For All (All pilots can multi-target, but the aim chance degrades the more secondary units are fired on)
- Random Rookies (wider random variance for new pilots starting stats)
- Hidden Potential (when you promote a soldier, their stats increase randomly)
-
Design Quirks (Mechs that have canon quirks are applied, some are positive, some are negative or have both) For Example, a Banshee has Negative Perk "Bad Reputation" 3 Series only except 3S making resale value cut in half and has Positive Perk "Distracting" - Morale drops for opposing unit in same hex
- Rapidfire Regular Autocannons (you can fire an AC twice in one turn,
but it can jam rendering it useless)
- Table Top Ammo Explosions (more deadly ammo explosions)
There are plenty more TacOp Rules to gain ideas from.
Other than that, features like being able to mount a weapon rearward or flipping the arms to fire in the opposite direction would be super cool and add an extra layer for firing arcs/tactical decisions. Dump Ammo would be another one, useful for more deadly ammo explosions.
