IMO, the name is no problem.
Your knowhow to get in contact of a publisher and to convince him to take a look at your demo - that's the first step.
The second step is to convince him that you have a good and reliable team that delivers the required quality in time.
If you managed that, the engine doesn't matter at all - as long as its for PC only.

You're right, I've never before noticed that.

Gamestudio is called gamestudio because one of its primary features is that it comes with everything you need to build a 3D game (in contrast with other engines, which come with nothing but an engine and a script editor).

Acknex is a cool name (indeed one that's used by the actual engine) but in my mind it fails to emphasize this core feature.

name does not have to do anything with features. Unreal engine is not named unreal because it's unreal. Or other engines Torque,Shiva,Unity none of the names suggests anything about the feautres. Also except for model editor, most engines come with nice level editors these days.

Okay, lets look at the names of competitors. Torque, Unity, Unreal, etc.
They all have one thing in common: The letter 'u'. So what Gamestudio needs is a 'u' in its name, so what about... GamestUdio?
Sounds really cool imo.

Or Ulillillia.
