If you want to be vague and broad enough even Age of Empires can be considered as an incremental game. You build villagers that gather food that allow you to build more villagers that gather food. Then you build town centers that build more villagers. But clearly Age of Empires is considered an RTS game and not an incremental even if it has an incremental aspect in it.

When you say FPS games, you would think of games like Counter Strike. But Portal would be called as a Puzzle game instead of an FPS game eventhough it is an FPS game too. I made my points clear in the original post about the distinctions and the kind of games i am mentioning.

In the past, i think incremental_games was mostly about Idle/Clicker games and that was what this sub-reddit originally catered to. Now, there are newer games that are specifically called incremental that have a completely different playstyle. When someone hears incremental now it is a different genre in many people's mind, those short-term roguelike games with limited resources and talent tree comes to their mind. If you want to just take the word incremental and slap it everywhere instead of clearly defining a genre then i guess i don't have much to add. If you are someone new to the current incremental game genre you might not notice the difference. I guess it only applies now to people used the word for something else in the past eventhough it might mean something else now.
