I found some video gameplay of Farmer's Dynasty, but it's so old, and therefore I don't know how often this game take updates and what kind of updates.
Can someone help to take all around info of game.

Hi, I definetely think it is worth a try. If you don't expect too much and if you just want to spend a relaxing time while building up your own farm. I would think its a game for beginners to this genre and you should not compare it to other simulators with a huge amount of machines and top-realistic mechanics. But there are so many things do do. It includes some mini games and quests from other NPC's. Maybe you should visit their page to check about the updates.

Thanks for reply, I'll try Farmer's dynasty, want to play this sort of games (^_^) and maybe write some words about my impressions from game.

I'dont recommend this game, it's an unfinished one. No more updates, the finished game is like the early access.

I'have played 17 hours, there is too much defaults.

56 Hours on house flipper,
81 hours on Euro Truck Simulator 2,
182 hours on Farming Simulator 2013,
110 hours on Farming Simulator 15,
...

It is very boring and not very well finished.

So, I gave it a try and now can say - this game didn't live up to my expectations. Graphics pretty well, BUT sysrequirements are ridiculuous. Machine (of such config FX 8350 stock + 16 Gb DDR3 1866 Mhz RAM + GTX 960 4 GB and little overclocked + SSD) cannot handle 60 stable FPS, WHAT??? Also game mechanics so basic and in some cases absurd. So conclusion - don't buy this DEMO (or Tech Demo) from Devs, because you can find alot better games (like Farming Simulator series or other).
