Research is great, right up until you finish the techtree, all your labs become obsolete and a great hole for shoveling resources into is gone.

Combat removes resources, but its more of a penalty than something you spend resources on; tower creep can effectively kill anything with ZERO cost, the other methods are just easier but expend more resources so you're just paying for convenience rather than to accomplish something.
I would really like to see infinite research added to the game, it doesn't have to be practically useful, it can be really stupid bonuses, like +10 joule to the fuel value of coal or +1hp to your character and cost thousands of research packs, that's totally okay, it would just be nice to have something that will eat up resources and give some kind of benefit, no matter how silly.
I really hope this is something you'd consider working on because a lot of these survive and build games, minecraft, terraria, don't starve etc etc, have a hard ceiling for how much of a resource you can actually spend and once you're done spending it is effectively worthless and only used for cosmetic fluff. Factorio takes the production much further, and it takes a long time before you get to the limit but once you're there it sucks the fun out of the game very quickly. I'd love to build a nice research compound with lots of labs, it's own assembly lines for science packs and a train station for delivering materials to be eaten, but there's never a point; i make my starting setup and just leave it running until i'm maxed out scienceways.

I don't know how you're going to do oil yet but i'm hoping maybe fuel can be a thing that's infinite but extremely costly to mass-produce maybe? Anyway, anyone else hoping for something to build lategame?
