Now as for whether the ULTIMATE EDITION (I bought it for 30€) is worth it compared to the other 3 versions in terms of cost, I don't know, maybe not because it doesn't offer something so great anymore (YEAR 1 PASS, COSMIC PACK, SKULL 'N STYLE PACK, RAINBOW PACK, NEON PACK and +20 HELICOPTER TICKETS), but as a fan of STEEP, it goes without saying that I would buy the ultimate edition when I found it a few € more than the standard edition and considerably cheaper than the gold and freeride editions for some reason.
I will say that I am very happy that they released something similar - with a similar philosophy to STEEP (especially as an old fan of SSX, SSX Tricky, SSX3, downhill domination, etc.) and of course it expanded into new territories (bmx, etc).
