How much am I missing out on? Trails series question

Board 8

I played Sky 1, SC, 3rd, Cold Steel 1, 2, didn't touch the fan translations (nor do I plan to) and didn't have a problem at with following and enjoying the plot of Cold Steel 3. Nor did I feel like I missed out much with spoilers on the Crossbell games since I don't think I will play those games unless they get localized anyway.
