"Construction by games" ? Sounds way cool.
Have you checked yet the still unfinished (as far as I know) "meaning"
series of papers by J-Y Girard ? They expand on game semantics and boldly
go further. I have used the following address http://iml.univ-mrs.fr/ftp/
to access them, but it doesn't seem to work lately.
Best,
Youlian
