Reasonable on 02 April 2008
Pacing is going to vary according to what you want.
For example from my point of view COD4 has no pacing in the traditional sense as it does not convey a story with traditional arcs, etc. - i.e. each level is distinct from the last and complete in itself, while each level employs a simple pacing tactic of increasing difficulty / impact through to a climax.
Half Life 2 has pretty good pacing in terms of story arc balanced with gameplay as does Halo.
But that's because I prefer story led experiences to pure gameplay led experiences - which is just me and not some universal truth.
Try to be reasonable... its easier than you think...
