That implies that their games only exist to sell DLC, which is unfair, I think. They make a lot of DLC, yes, but they keep updating their games for free, years after release, and people still buy the DLC anyway.
The trouble is that quite often their numerous DLCs "break" the base game. Im often reminded of my time with Stellaris. And i was really annoyed that i had world events that i literally could not complete because i did not have the relevant DLC.
