Good support is not to drop games to linux, but to build with linux tools, keep the software up-2-date and fix bugs.
Sure they drop things to linux but then build for a "bsd" system (dont use gnu-libc but some own thing (i think). That why the games do not run when you enforce libstdc usage. (fun fact: thats why i've started the rewrite of the steam-manjaro pkg) and do they fix bugs? I dont think so..
Good suppor: Feral Interactive . Supports answers, asks the community and fixes bugs month later (+ they even help the Mesa guys!).
