Some time in late January 2019, Steam starting prompting people that there were updates for TRON 2.0 and TRON Evolution. (Didn’t notice any mention of TRON RUN/r.) But it’s not what you might think.

The updates weren’t issued by Disney. They don’t patch the games.

These were updates issued by Valve, and they have to do with reducing the amount of disk space used by all the games in your Steam library. (So you should be seeing updates for your other Steam games, all at the same time, too.)

Many games come with what are called "redistributables", libraries of code that the games rely upon to function. They need to be installed first, before your games will work properly.

The problem until now was, every game came with its own copy of the redistributables it needed. But what if several of your games used the same exact redistributables? Why keep multiple copies of them? Why not share one copy of each redistributable, amongst all the games that need it?

That’s what these Steam updates to TRON 2.0 and TRON Evolution were about. Consolidating these redistributables so they can be shared among many games, and therefore stop wasting disk space (by not keeping multiple copies of the same thing).

If you’ve patched or modded TRON 2.0, this recent update should not affect or break your game installation in any way. I discussed this with someone on the Steam forum a bit more in-depth.
