Best and worst most extreme departures long running series have taken?

[Leynos]

Best.  Front Mission Gunhazard. Series is normally a SRPG where Gunhazard made it a side scrolling ARPG. It plays like most side scrolling SNES mecha games but it has RPG elements and a Super Mario Bros 3 overworld. The OST is phenomenal and some of it sounds like prototypes for FF7 songs.

WORST. DmC Devil May Cry. What a giant giant turd. The edglordy cringe tone and dialogue are made by a mid life crisis edglord moron for edglord morons. The dumbed-down combat. Until the day I die, I will piss on this piece of shit's grave and am so glad the real DMC is back. With Kamiya doing Okami and he expressed interest to remake DMC1. I welcome back the king.
