It is a german game, but there is an english version of it.
I could not find an english review of it though, so here is the link to the only german one I found (pictures speak international
).
Mag!!!
For me it was always one of the best of its kind, very detailed game and you get a close feeling to your company, which is important for me.
Have to say that it is very difficult to run a profitable mag in that game, but I suppose it wouldn't be easier in real life.
You start at the Atari / C64 age and can go up to 1994 I think, so starting with a PC only mag at the beginning wouldn't be that wise because of the lack of any games to review.
There are also a few original game titles (slightly changed) with original PC Games or PC Joker review but if you really invest some time in it you can add all the games and even staff to the game that you would like to see with the editor.
It has also a prebuild import option to load editor files from fan sites, but I don't know of any fan sites existing anymore.
