@Shane McGrath UI. The people who made games with 3D graphics, all reported that Grok's quality was a level or two behind Fabel and Sol. It was actually a Cursor hosted meetup, so many people started with Grok 4.6. But more than a handful switched after a couple of turns. In contrast, people who started with Fabel or Sol got a more "AAA" game look and feel in fewer turns. Still, it seems like the core game mechanics and functionality worked across the board, regardless of the model.
