Hm, the tone I seem to be getting from 4e DS is a little bit of a more restrictive version of that. It's like "if you want it in there, it's in there," holds but "only if it makes really good sense to do so and you have a way of twisting it."Stumblewyk said:The tone and tenor of the 4e Dark Sun material seems to be "if you want it in there, it's in there," as opposed to 2e's DS model of "only what we allow."
If anything, the Dark Sun Campaign Setting is less afraid -- compared to ALL the other setting books -- about 'kindly suggesting' not to twist things against the intended ecology of the world, but while retaining the 'it's your campaign, and if you're the DM then do what you want' tone that permeates the aggregated 4e literature so far.
In any case, I'd totally have more chitinous or reptilian versions of beholders or play up their aberrant keyword rather than just plopping them in unmodified.
