From start - this game is very fun, detailed and fascinating. I can really play it for hours, it has enough graphics and great gameplay. It's a great manual for novices to know - how work your PC and what parts you need to make it works. But also there is some bugs and imperfections to give more stars to this game. 1) Graphic engine. Sorry, but when you're emulating 1 room with almost static content - you shouldn't use so much resources. I'm getting my game laptop very hot after 2 minutes of playing. But i think it depends from selected Graphic engine (other sim games using this engine are greedy for resources too) 2) Some parts assigns to user when detached, some not. You can disassemble whole PC - and almost all parts will have sign. But if you don't remember which Power supply or RAM or Cooling system or smth else you've detached - HAH, MAN, IT'S YOUR TROUBLE! 3) There is no any notepad or link system for shop. Yes, i want to order some parts and attach it to concrete order. Or have ability to make any marks on orders. 4) In Russian translation some language phrases are overlength so sometimes i can't get needed information and had to switch to English 5) Diagnosis and FIx mode. Sometimes EXTREMELY terrible. You can disassemble almost all PC, replace ALL broken parts, run 3DMark, Antivirus and made all needed things. But this requirement still stay red. Do you really know what do you need to make this thing green in some cases? Ah, ok. You forget to remove 1% of dust. To remove this dust you should rotate pc on strange angle and pick cursor on small area which are located on backyard of this PC case. I've about 10 similar cases and i was needed to decline this cases with money and rating looses because i can't understand what actions game's creators are required for me. But... Guys, this game costs 5 bucks. It will be your best spent 5 bucks of a Year if you're really like working with PC.
