A very quick entry for now, as it has been suggested that there may have been a US version of Strider in development, before the Tiertex version was used instead. This was found via a comment on a Battle of the Ports video.
At the moment, there is no evidence that a different development was under way – and more research is needed. Perhaps there is something in the US magazines of the time that mentioned a particular developer working on the game. Did someone like David Bean (who did US versions of Cabal and Ikari 3) perhaps start one?
If you know anything more – please let us know, though it is likely that this is vapourware.
