Affixing is horrible in PSO2. It is enough to dim my enthusiasm over NGS but I am willing to let it see how it has improved and streamlined. To do it successfully you will need support items, which are bundled with the loot boxes that contains the skins, costumes, emotes, and accessories.
Monetization is F2P and pay for skins, and there are so many things you want to buy. The game is literally a cosplay festival. There are support items that you may need that are bundled with the gacha skins, so rolling for the skins, you may also get these.
What I don't like is the pay to play triggers. You get some free, and you can ride along and party with your clan members and friends that got their free tickets but eventually you will have to pay for these. The good items would sometimes and rarely drop on these.
What bothers me most about PSO2 is the inventory wars. Breaks so much time trying to manage inventory, sorting out the good pieces from the garbage. Farming for affixes makes it even worst.
The second thing that bothers me the most is that SEGA absolutely has no idea how to design a quality user interface.
But if you're here for PSO and NGS, you're here for the action, among the finest you will ever see in an ARPG and MMORPG. On top of that you can totally weeb out in this game, everyone is here is a weeb, weebier and weebiest.
