>need alternative fleet battle games to SW:Armada
Full Thrust (FT) is an oldie but a goodie. Very generic by design so it can fit into any universe (SW, ST, Halo, etc), includes ship-building rules so you can make the fleet you want/that fits your models/universe.
Firestorm Armada (FsA) was a game that sort of took FT, and made it more complex without being much more complicated, although it included some stuff that I didn't really enjoy (why does everyone have MINES?!).
Both FT and FsA sort of turn into slugfests though, with the largest ships generally being better than an evenly-costed amount of smaller ships thus resulting in Capital-only brawls.
There is the old-but-might-be-revived-soon game of Battlefleet Gothic, which is an okay age-of-sails-in-space fleet game. If you are not into WH40K fluff/aesthetics though you should probably steer clear. (also its been 4-5 years out of production so getting 'proper' ships for it will be fun)
The most recent big fleet game would be Dropfleet Commander, which although I am only starting to read up on, has many positives (battles are not straight slugfests, you actually have objectives on the board that make sense and your objective-capturing ships are not paper-thin. Factions are all pretty diverse as well). Do beware though, the models have LOTS of little details, so if you are like me and hate the painting part of the hobby you will be in for a fun time with them. (I also think they are overpriced for being all-plastic but I guess you pay for the details)
>All I ask for is fun rules and cool minis.
That is all anyone asks for, but the issue is that those things are subjective.
By generic do you mean FT-style games that are meant to be bent to other universes and include rules for making units?
For Dirtside II, there are alternatives to the chits, but they are usually more time-consuming than just using chits (see img). I also am not a fan of chits but I recognise their utility in DSII.
