Final Fantasy XV’s development is coming along well, with the team recently hitting a milestone this past October with the completion of the game’s pre-beta stage. To put it simply, Final Fantasy XV is in a state where you can play the whole thing through from the opening to the ending and the development staff are now able to get a feeling of the overall game.

Adding to his initial post on the game’s official forums, FFXV programmer Satoshi Kitade noted that the pre-beta build is currently running on both development PCs and on PS4, though the latter still has areas that require optimization and adjustments due to memory.

Memory optimization is a big deal and is the main reason why the dodge roll mechanic wasn’t included in the initial release of Final Fantasy XV Episode Duscae. According to Kitade, because the memory that can be used is limited, developers have to compromise when they go through adjusting parts of the game. It’s up to them to decide what can and can’t be added in based on the different parts of the game and what resources are being allocated to each one.

Adding the dodge roll was something that had to fit into memory along with all the coding related to avoidance and is the reason the specific action wasn’t added in until version 2.0. Because the final game is being developed on under different circumstances, the restrictions back from the demo days don’t necessarily hold true today.
