I was verry disappointed when I played Tales of Monkey Island when I saw there were no french dialogue. For me, when i see "French version" on a box, it means that everithing is in french, including dialogue. For that, I hesitated buying Sam & Max: The Devil's Toybox, until I learned it was the same case. I guess it will be the same with Back to the Future and Jurassic Park ?
I pre-ordered BTTF Deluxe Edition only because I knew there would be no french Deluxe Edition. I planned to get the french version to put it in my deluxe box. I also planned the same for Jurassic Park. But since it goes that way, I took a decision.
Until you release fully french versions again, including past games that aren't, I will not buy any more of your games.
