I wanted to include steam game info <game_name>, but that requires to fetch a gamelist (returns json with some 30k records) from steam every time a request is made and then pass the matching id for a spice call. Im not sure, this scenario fits the spice IA perfectly, what to do? 
Also please advise on the pending issue with pr #846 and #845(use of spice wrap_string_callback), so i can update accordingly. Ty.
