Actually its more about the removal scenario, lets say someone does:
df
yum install vegastrike    (drags in vegastrike-data)
df                        (who thats big)
<play vegastrike>         (hey that games sucks and eats up my HD-space)
yum remove vegastrike
df                        (WTF, why am I still missing 0.4 Gigs of HD-space ??)

But that isn't much different from a case when I install any package
with rich dependencies, say, gnome-session and after removing the
package there will be dozens of packages left I didn't want.

Actually, the loop may cause that I won't remove the game, because I
forgot I've installed it and it doesn't show up as a leaf.

Until yum or rpm is able to track packages installed only to satisfy
dependencies, this will always be a problem. Why make the game data a
special case?

Umm... agreed.
When I install some binary rpms rebuilt by koji scratch build to review
the package it often pulls so many depdendencies, especially when they
are Java packages.
In such case I usually keep the log what yum installed to satisfies
the dependencies, and when the review finishes, I remove all the rpms
written in the yum log.

So while I can understand the idea that game maintainers want yum
to remove both program rpm and data rpm simultaneously, I don't think
this is the strong support for making intentional depedency loop.
