Well, thanks for your anwser
I'll try with SpriteFont then, I tried the "outline" effect too but the line color can't be changed (white) and it's really ugly (pixelated).
Edit : little problem, the SpriteFont's download link is broken
This is all you need to get you on your way.
grab latest version GiveYourFontsMono(spacing) v2.2
Once you created spritefont it is in png format. Open in photoshop and change the font to what you want.
It takes a bit of work to get it just right, but it is worth the effort.
Then insert spritefont into your game like and it has default which is ugly, open and browse for you spritefont png. Don't forget to ajust your character widths, hieghts etc as whatever you choose them as
