I'd have to agree that a better UI is needed. It will be needed even more if the game is s 64 bit and the unit caps are increased.
Let's say that the game remained real time and most of the wishes remained true. Scale of Sins 2 will be larger because it's 64 bit and unit caps may be higher.
- The problem is, you've got multiple star systems, multiple fleets, and multiple battles of several thousand units.
- In fact, there may even not be a unit cap (like other games, it may be a function of empire size)
- If the scale goes up, then the difference between Titan to say, Strike Fighter would be even bigger, which would introduce complexity in other ways. Tech tree, which units to allocate to what, etc.
Other ideas include:
- Customizing your own weapons per ship (should be limits, otherwise for example, everyone would choose the best weapons, like everyone using Phase Missiles)
- Designing your own starbase or Titan
I agree that the game could be made good if there's a better UI even in real time.
To be honest, at this point, lack of ideas for improvement is not the bottleneck. Perhaps neither is hardware. The real problem right now is that there's no indication that Sins 2 will even be created or is in development.
