> Is this typical of games these days? Do a crappy "main" game but "fix it" with DLCs?
A lot of AAA devs have started using games as a platform for DLC. Valve, for example, just launched glove skins [0] - 300 USD for a texture. DLC is far more profitable than games, nowadays.
As for Bethesda, long-time fans have a general understanding that Bethesda games get worse with each iteration. Their DLCs are usually better than the main games, but not by much.
