should i play this first or Sharin no kumi
I would play Sharin no Kumi first. Instead of going backward from G-Senjou that uses newer system to older one, it would be better to play the older Sharin first. Also, compared to G-Senjou, I found Sharin to be less engaging, maybe because of the expectation I held after playing G-Senjou. So playing Sharin first then G-Senjou might be more rewarding.
