I could see them making the games free in years to come. Maybe a good thing to introduce fans to the old ones.
No doubt. Many people were introduced to their first two TES games in the same way so that could be a high possibility. I wouldn't leave out porting to smartphones though. That seems like a popular thing to do and fans clamor for it. While you can drop the files and run DOSBox on, well, confirmed: WebOS, rooted Android, Jailbroken iOS, it doesn't work out too well. And InXile also did mention if Wasteland Kickstarter went through and say the game launched on PC it'd make sense for mobile devices as well. I don't see Zenimax backing out from simple porting jobs to assign to BGS or other bought studios. Lots of money, and even I would buy it up.
-Cough- Although it wouldn't hurt if when they do go on smartphones if they tasked themselves or someone like Obsidian to make a isometric FO side title on them. Think what's happening for XCOM right now.
I'd definitely go for that, even though as an RPG fan I never liked the CRPG approach of trying to emulate pen and paper/ turn based things as I feel it never wholly worked.
