About Indie Games (I try writing in English)

Indie games and indie developers are not familiar on the Internet in Japan, but in recent years I have come to hear whether smartphones and mobile games are exciting ... I feel like I was doing. In general terms, I think it means an independent game company or a personal game. Actually, events such as BitSummit only for indie games have been held. (I have never been) With regard to the largest bitsummit in Japan, the exhibition is about 100 groups that have been judged for about 10,000 visitors, and it is no longer a minor cultural event. However, there are many big game companies and distributors in Japan, and the amount of so-called copyright doujin contents and events are amazing, so it seems that the shadow is faint. In fact, there seem to be many indie games on display at the Tokyo Game Show. Is it influenced by the fact that a lot of game engines and tools that appeared when I was a kid made a lot of personnel and a lot of money, and that it became easier to develop? It seems to be an event held in Kyoto, but I want to go someday.
