@MasterDarkwingz Nexon is also notoriously predatory in their financial methods and as a result has essentially killed every single one of their MMOs.
In PSO, it costs money to reset your skills, or change your pet, but you're still handed a free one. The lack of tutorial is where the major issue lies. Just like other MMOs, though, there are opportune events and mechanics to keep your fashion up to par and your skills meta.
In Nexon games (Maple, Dragon Nest, Vindictus, even Combat Arms), while there are still events that can help manage your builds, leveling is absolutely impractical and unfeasible unless you only play that game for months on end and not leave the house. They are notorious for this and have basically designed all of their games to be impractical time sinks. You can then buy experience boosts which just BARELY increase EXP. You also aren't handed anything except when its completely impractical (skill resets extremely early in the game). At 93 cap level in Dragon Nest, a Nexon ARPG I played religiously, it took an obscene amount of time to get from level 90 to 93 if you did every daily with an experience scroll AMP and ran dungeons afterwards for at minimum of upward 8 hours. Maplestory was also like this, as was Vindictus. Quests gave you, quite often, less than 1% EXP. But you could speed up runs by paying for better gear and buying more EXP increases.
On the flip side, in PSO, leveling is quick, making new characters is quick, skill optimization is quick, and its actually been alive for 8 years because it's cared for to an extent. The pay2win elements, while present, aren't present in the combat interactions, and more so in storage capacity.
I understand your criticism of the lack of explanations on items, and how predatory some of the game can be, but using Nexon as your gate of the moral highground is kind of strange given Nexon's history of killing the games they touch, regardless of their quality.
