Been waiting for BFG edition since it announced, and all they did technically was turn up the brightness in all levels.
so finally after 8 years of waiting they released BFG edition with much anticipation i got this game on its first day of release, i wasn't interested in doom 1 and 2, but i just wanted to see what are the improvements in doom 3.
and the one and only visible improvement i found, was good amount of brightness level and the secondary improvement was computers and pda graphics.
a few new missions called the lost missions (which are the only thing good about this version) bundled with pixelated scaled up versions of doom1 and 2 and the resurrection of evil.
and here you go BFG edition.
In a few words of wisdom, if you own original doom 3 and ressurection of evil for PC, consider BFG edition a ripoff.
Again choice is yours, like it was mine.
