PLT Scheme still doesn't have a meta-object protocol, right? So it's still a ways behind Common Lisp the language, in my opinion. However, as far as the implementation goes, PLT Scheme is really nice and fully-featured. It also has one feature I like a whole lot: it's fully embeddable. As far as I know, neither SBCL, nor Allegro CL, nor LispWorks, nor Clozure are (I know ECL is, but I also don't know anyone who uses it). This makes PLT Scheme a reasonable choice for something like game scripting.
