Summary:
-MW's Tarantula is a MOD from SB's Roller Coaster.
-SB's Animator1 has graphical similarities to MW's tall sprite games, and Merlin has code blocks that load directly into Animator1.
Googling shows that MW is the label, and SB is the nickname:
I don't think this was noticed when Pete first mentioned. It looks to me like they should be linked. All say aye?That's a pen name for Mike Westlake, it has to be. SU directs you to send a cheque to "B.C.S." to a "Grantham House" in Macclesfield. The Softcat Micros address in adverts was a PO Box in Macclesfield. A bit of hardcore Googling shows a Mike Westlake is a member of a Macclesfield local Facebook group, his profile shows he's following LOTS of Facebook pages dedicated to satellte TV dish installations. Googling on the Grantham House address reveals it is (or was) home to 'BCS Satellites'. I would say that Mike Westlake and 'S Brocklehurst' are the one and the same.
The only thing I find strange is that his games started out as the nickname, and he adopted the real name later.
