Close!

Indiana Jones?

Far!

Mr Pumpkin Adventure?

What a good guess.

Trog the Frog

¬_¬
Take example from @Gigglemoo, and at least try to come up with games that exist.

Well I couldn’t think of any Speccy games ending in (what looks like) T. Is the game title in French (or language neutral) too?

Yes it is, and this is not a T (I’d never thought this would be a potential red herring, bad crop on my part!)

Looks like a fancy L to me. I’ve got nothin though. :)

Teenage Mutant Ninja/Hero Turtles?

It’s not a letter… Although, it kind of is… damn.
Anyway, everybody’s getting colder now.

I don’t know anything about the Amstrad et Spectrum platform, but maybe some of its games were on other platforms.

My vote is for the game Chiller.

I have good faith the Britain crew will spot it easily. It was pretty big!

Witch + pumpkin = Cauldron?

Nearly so!

Cauldron 2!

(It’s the nest logical step, given the letter-not-letter)

@Gordon_Cameron will have been completely robbed of victory if this is even a game, much less a winning game.

I was a terrible game, even more terrible than the evil first one, but it was a real game :O

I have stolen victory, much like the jerk on Price is Right that bets only $1 more than everybody else.

Onto the next game:

Homeworld?
