Chaos Sector / Chaos Galaxy are games obviously inspired by Super Robot Wars (though not quite the same kind of tactical experience). Basically strategy games where you build up your forces of battleships and mechs to take over enemy planets.
The setting is very "space ancient Chinese empire which is on its last legs and needs to deal with rebels and invaders gnawing at the cracks", get to choose from various factions to play as.
Panzer Paladin is a good retro platformer where you're a super fighting android piloting a giant robot armed with various destructible melee weapons you can break to cast spells.
In-game there's actually an editor that lets you design and stat out weapons pixel by pixel which then can be dropped by minibosses.
Also you can jump out of your mech to fight on foot with a laser-whip, its required for some sections where you use the whip to swing between hooks but it can also come into play when the robot gets taken out of action like in a boss fight, possible to continue on foot and win.
