Like Sunset Down , I think authors have reached 3DGS limits or have targeted too much And i can say what we've seen was only little showcase of very good textures and some good models : only 3D art showcase.
Far from a game level with ennemies, a real level , LOD used by the engine, particles and shader effects, some AI. I think like Sunset Down people , and i perhaps , they 've seen what means and how incredible work/patience/time consuming can be a game.
People should lot more target more little games, why not some arcade ones like Daytona USA , some mario kart like , Crisis shooting game with some additions ... simple but fun enjoyable games
