It's been a really long journey with this game, now the servers will be shut down in February so I'll stop playing with all I did for years and there is no hope for an offline version; anyway Opera Omnia proved to be a really good gacha, the pulls and farming were really generous maybe the most generous of all the gacha I've ever played
I really liked the plot, the first two seasons were practically an adaptation and expansion of the plot of Dissidia NT and then continue with the last two seasons with unpublished stories, I really hope that Square Enix changes its mind and releases an offline version...
