Both these games here picked up and are in still in production.
Shadowrun, is up to at least the 4th edition rule set, but is still primarily a role playing game.
Battletech is going in two directions.
The folks at Whizkids are producing a version using their dial base system.
Then there is the so-called Classic Battletech.
I don't know how classic it really is, since they include that 3050 bullstuff, which is fit only for momma's boys and NAIS grads.
Except for the powered infantry armor, which is cool.
