I mean, not really? If anything, other than visuals, animations, sound design, etc - Bend's game feels like it's being more ambitious than even some of other Sony's AAA titles.
- Decently sized open world game. ( Based off the rough estimate of the size of one hub and the fogged map that was in previous teasers, the size of the world will be substantial enough to be believably sold as an open world game, even if not AssCreed or RDR2 levels for obvious reasons )
- Day/night cycle with weather patterns
- 30 hour long story campaign ( according to the devs, even if we trim it down to hyperbole and it's actually only 20-hours - it's still substantial )
- At least 4 different combat-related open-world activities ( hordes/human enemy camps/freaker breeding grounds/NERO checkpoints)
- At least several typical open-world style activities ( side-quest/collectibles/towers/bikes/etc)
-Pitched or positioned to be a rather 'dynamic' open world, one where enemies have movement patterns and a degree of randomness. ( enemies will sleep at different times of the day, stronger in cold weather, will move around the map, won't just be in one location, etc etc )
I have certain areas of concern with Days Gone even now ( tightness of gunplay, lack of hipfire which imo could make horde clearing unfun, poor sound design, and animation that isn't as visceral or well-animated as the WWS peers ), but otherwise it looks to be plenty worthy even just looking at its checklist of features.
