So the following Principles times, the eternal nagging about the Steam application I can no longer hear. Either one may not Steam, please read the product description carefully before (and not complain afterwards) and stay away, or you can live with it, and actually very good. I was on top of Steam (Half Life 2) also not a fan of this service to be able to play registration forced to, server bottlenecks Steam where you still could not properly use a lawfully acquired game impossibility of resale etc. But now I am a become a friend of this service and have, since the benefits easily outweigh the meantime more than 30 games in my Steam library. All settings for the game are stored online, even the progress! Is, in a HD error or system change I can afterwards at the exact spot to play with all the once tedious zurechtkonfigurierten settings as before, no tedious Readjust and configure and repeat all already played portions super !!! And performance standard, there is also nothing to complain about, especially since all the games are automatically kept in the library of patches up to date without my help! No more searching for patches on the Internet and manual installation. So Fact: Steam should not be a criterion for more games recessions! But down to business: The Bausimulator is great in my opinion. Have spent much more time than we thought, because it simply is fun to fiddle around with the many equipment. OK, the performance of the trucks on the road comes a DTM vehicle very close ;-) but well, the actual simulation will stop at the construction site instead (No truck simulator) and there goes moderately fun really off the post. The only problem for me is currently still (hence only 4 stars), which in the city often gets out the program abruptly, and I just again land on the desktop surface without an error message or the like. Only happens in the city, village, country roads, dams etc. no problem, so I have the framerate in suspicion. Although I have a very performant computers, run on the yet all current games (eg watchdogs / NFS The Crew) in every detail at 1920 x 1200 liquid!?! Therefore, no breaking the frame rate in the city is also the BauSIM 2015 note, it runs smoothly and soft and they marveled at the attention to detail such as church and square and so on, and then Peng, I'm suddenly on the Windows interface. But I think that this will also shut down with the next patch. In the beginning it was not even with me. But as described above, just wait and see in the Baubude NEN tea ;-) And then, the program has clearly earned 5 stars!
