We're trying this for a week or so at the house. Pluses and minuses so far .... the Source game engine obviously has a lot of potential ... be interesting to see if the design team takes this past the hints of the potential.
Random notes:
UI Mode switching takes some getting used to if you're used to FPS or typical MMO layout. Not nearly as bad as some games since the WASD layout is still core but still tinkering to see if some anomalies can be corrected (like the WASD not really being an "over the shoulder point of view").
The initial 3 characters (2 female) are obviously giving a lot of the less secure players some issues with their delusions of manliness
... the player base seems to have a large percentage of the "usual idiots" and the chat tool doesn't really help much to manage that. chat spammers make town chat basically useless. Chat tool is .... awkwardly ancient feeling and lacks a lot of usefulness (e.g. "ignore" feature?).
Actual combat mechanics and effects are very fun, I like actually being able to run behind a pillar to avoid arrowfire and catch a breath. The mobs seem to have the same restrictions - they get tired, they miss, etc.
Okay, having equipment damage actually reflected on the character is very cool... minus points for it all automatically being fixed on return to town. You have to go shopping anyway so it'd be more immersive to have the vendors fix them. Crafting is interesting (as in you bring the mats in and the vendor does the work).
Meh, there are wonky bits common to many f2p mmo... the setting is interesting (Dark Age of Camelot feeling) and you get used to the goofy "visual novel" interactions (with no way to speed up much of it). The instances are nice, remindful of DDO so you're not annoyed with idiots while you're questing.
So far, pretty interesting AS LONG as they're clear that it is still pretty skeletal in a number of ways.
I will never understand the "korean" fixation on not letting you reroll characters with the same name. Sometimes I'll design a character, get ingame and figure out he/she looks like crap or that I don't like the class... so I reroll and most games let me reuse the name.... but not many Korean games. Some of them forever bury the name, some make you wait a day/week. The most hilarious was one game that locked the slot with a crying character for a week before it died. Every time you logged in the character stood in the character choice line begging you to save it
In general, I'm giving it a thumbs up so far (only gotten to lvl 15) though - free is good, though I haven't really looked to see if the cash shop is prudent (like Grand Fantasia, DOMO, etc) or a rapefest like the EQ2 F2P version is (I play eq2 over on the monthly sub servers).
