I wish they'd upload the TL port to Steam and port TL 2.
I bought it a year ago but I can't get myself to boot into Windows anymore.
That'd be lovely. However, it's not likely to happen - and is the main reason people who cry "get Ryan Gordon to port X" are missing the problem.
3rd party porting is done on a contract basis - either a fixed price contract for a fixed set of acceptance criteria, or time & materials (however much they may be) at an agreed rate towards a set of acceptance criteria.
If "Get SteamWorks implemented fully and upload to Steam" wasn't a specified requirement in the contract, then it won't magically happen.
Either the developers themselves need to do it (unlikely if they contracted out the port, as they'll have 0 Linux expertise on how to do it), or pay someone to do it (unlikely as that costs money).
Other things, like bug fixing, will need to have been part of the original contract, or a new contract - or not happen
In-house porting is always better than contracted porting, from a "sustained support" perspective.
