These are the games that are often overshadowed by the larger, more popular ones but have the potential to be one of the best if they were to be continued or certain aspects of it were fixed up. Feel free to add in games that are somewhat popular online or offline.
Feel free to add in games, you think that had the potential but developers screwed it up with its sequels and how.
For me, Machines by Acclaim Studios was the very first game I ever bought. And I still have it, despite it's extremely old age it is very unique to any other games I have played so far. Put it simply it is a R.T.S with robots, but you can actually 1st-person pilot the units themselves. If you know a game that can do this, please tell me. There are so many units in the game and just as many in variety in weapons and designs. Sadly, Machines 2 never got released because Acclaim got closed and bought out. I think Combat Arms by Nexon actually has more customization choices than the recent Call of Duty games, would make a marvelous MMOFPSG .
I've never heard of that game, but it sounds interesting, I'll have a look. There are other games of that style, though they're quite rare - 'strategic action' is what I call the genre myself.
Personally, the game like this that I love is Brutal Legend. It's set in the Age of Metal, an alternate history period which is basically the crazy stuff you see in heavy metal album covers brought to life. The setup of the multiplayer is basically a battleground with your faction's stage at one end, your opponent's at the other, and your aim is to destroy their stage.
You can create units, upgrade your stage (which serves as your base) and direct your units around with simple commands like any other RTS, but it doesn't have the emphasis on micromanagement or base building. Instead, you play as your faction's leader and can fly around to see what's going on, or land and just kill stuff yourself with basic combat using your weapon and guitar (which can summon stage pyrotechnics, basically special attacks).
But you can also perform Double Team attacks with any of your units where you will be invulnerable to being damaged yourself (the unit will take the damage instead) and can perform an attack which ranges from a controllable version of what that unit would do normally, to something completely crazy and different - like a unit which can summon a huge flaming stonehenge ring from the ground, into which a giant sword crashes down.
And on top of THAT, each faction can play from a huge variety of solos which each do something different, from summoning wild animals, to spawning a pulsating boil in the ground which explodes if an enemy touches it, to attaching an anvil to your opponent's leg, to crashing a huge flaming blimp onto the battlefield. It seems daunting at first, but once you get some practice, the different aspects of the game come together to make a game that's totally unique.
Sorry if I've seemed obsessive, but this really is an overlooked gem - so many people gave up when the game's strategic elements began to show, but if you just stick with it (and don't try to play it like a regular RTS i.e. flying in the air constantly and doing nothing useful or fun) then you'll find a game that's addictive and unique.
Other games of this genre are Sacrifice, Battlezone, Battlezone 2, Battalion Wars, and Pikmin (kinda). Of these I've only played Battalion Wars (for about 5 minutes) and Pikmin, but Brutal Legend is the most recent (I think) and is what I'd recommend.

It's on 360 and PS3, although the PS3 community is apparently pretty lackluster.
EDIT: here's a video of it if my crappy explanation was too crap.
