This is more of a wishlist than a list of actions I would do as CEO but I would like to see:
1. More than one main entry of Final Fantasy (not including a MMORPG) released during the next console cycle.
2. Move away from the serious tone of the recent Final Fantasy games and bring back some of the comedy and light-heartedness from the earlier ones.
3. Create a new intellectual property to try out concepts (e.g., open worlds, dialogue trees, non-linearity, etc.).
4. Develop the next Dragon Quest game for home consoles, return the series to a non-MMO format, and make it multiplatform.
5. Create a new tactics/turn-based game (perhaps something similar to Valkyria Chronicles or X-COM, but with more fantasy elements like magic, swordplay, etc.).
In general, I personally would prefer that SE move away from making re-releases and remakes, and focus on creating new games.
