Since the announcement of The Witcher 2. I was familiar with them before due to Witcher 1, but I didn't really enjoy the game to the point where I became a fan of the developers themselves. But TW2 got me hooked. I've been following them ever since.
Well, I've been buying games at gog.com for years, but I didn't know it was the same company for awhile.
Really these guys are few of the only devs in the true spirit of gaming, most are now just money hungry bastards
