I'm stepping away from Super Smash Bros because now I'm literally just grinding gold extremely slowly to buy the last ~60 odd spirits I'm missing, which are all just DLC spirits. It's not fun that way.
Bought Echoes of Wisdom, but my son's been playing it and I probably won't tackle it myself any time soon.
Instead I bought FFVII since it was on discount and I'd never played it before. I'm slightly disappointed after hearing it being hyped for 20 years - but it's still enjoyable enough to carry on with.
I've helped him out with just a couple of things, like a cloud boss battle, but he's mainly tackling it by himself, which I'm happy with.
FFIX seems to be regarded as a beter game in some ways, but I think FFVII is more iconic. I think I only ever tried out VI before (not for long, I couldn't get into it). I'm not sure whether I'll try out any others after this - I know there's IX and X at least also on the eshop
