So this is a continuation from where I left off. I think it's cool to have gambits on games that are team-oriented espeically when it comes to FPS, RPGs and beatem ups. Your team can automatically heal your teamates when their HP reaches a certain point; cover one of them if they are being attacked etc. Even in single play for RPGs and beatem ups especially if your character is a custom character you can set up the gambits to make things a little easier for you. FPS I don't think gambits for its single player maybe necessary maybe you can prove me wrong I like to hear from you.
I little more elaboration on custom characters it's good to have gambits of some sort because it could also mean the reflection of how you want to personify that character. For example if your character sees a barrage of enemies unoticed should your character automically decide to go in stealth mode and you just manually take them out silently or should your character go Rambo style and you manually beat the crap out of them?
