This video was originally put up by Fakk28, so I have to give him credit.
I Will - The Story of London is a mystery game where you have to find the Alpha Ozone formula. You can choose to solve it in 3 days or a week. Languages supported are English and Japanese.
I know that the acting and spelling are rubbish, no need to remind me. But I like the music you hear while searching for stuff.
The way they do the searching scenes is that the London streets are on analogue video, but the travelling scenes, the cursor and any text that comes up is produced by the Mega Drive Expansion.
The Laseractive was an expandable Laserdisc player. One expansion PAC made the LaserActive into an expanded Mega Drive that allowed the use of Mega Drive, Mega CD and LaserActive-only Mega-LD games. The other PAC turned the LaserActive into an expanded PC Engine that allowed the use of HuCards, CD-ROM² games and LaserActive-only LD-ROM² games.
