You're overlooking the fact that without a mandate to appeal to a larger audience Eidos probably would not have allowed the game to be made.
I think most DX fans would rather DX:IW never be made at all.
Even if you are aiming at the same exact audience number there is a motivation to change things so you are not making the same exact game. Reviewers hate this, many fans hate it believe it or not and even without a new mandate there is a heavy impulse to innovate, which is what happened to Tribes no doubt.
The issue with sequels isn't so much that they don't change, it's that they don't improve. A sequel should be better than its predecessors in all respects and most sequels don't do this. If DX2 had retained everything from DX but just made it better, the fans and reviewers would have been happy. Same deal with Tribes. With Tribes 2, Dynamix was trying make the game they failed to make with Tribes 1 (a vehicle-centric team-based shooter). They succeeded but ended up losing most of what fans loved about T1.
And on the other hand, unified ammo means you have more ammo available for any given gun, and don't have 700 rounds of ammo sitting there for a gun you don't use or are not skilled in, and no way of trading it in or getting rid of it.
That's one thing that DX definitely needed: vendors. Some way to trade your stuff. They could have put a pawn shop or something in the game. I'm pretty sure this is one change that everyone would approve of.
