Lags in multiplayer and Steamworks only, high demanding OpenGL sourceport with memory leaks prone to crash in bigger areas or when someone shot fire at you (SW Redux has similar problem but for different reasons), tied to Steam client, inaccurate lighting and sprites clipping not fixable even with retro look or Y axis lock, wrong skybox clipping, sluggish movement and often lack of certain quirks that classic enemies had, expansions by default only in Megaton source port, if you want them in Atomic you still need either unpack GRP or mod some con files so it's only 1 expansion per Duke3D at once. Also lack of D3D or Software renderer. Duke Nukem 3D from KillAToon Collection has NW, Vacation, DC and Zone2 for DOS version with nice launcher also Eduke32 included.

I always thought that expansions are lost forever or tied strictly for Devolver's Megaton Edtition but if they are included in 3DR KillAToon Collection, especially Duke Nukem 3D title I see no reason to not extend that for anywhere else besides Steam release and GOG's Atomic is signed under 3D Realms Entertainment / Apogee Software not Devolver so I think it's possible to extend these features from standard Duke Nukem 3D Atomic Edition to complete release of Duke3D.
