To make the current release date of April 14 the game should be almost gold by now, and it's far from it.
Before I talk about drawbacks, let me say it's the most beautiful game I've seen so far, really very beautiful. The action is straightforward and addictive, though there are questions about the long run. The idea of a persistent pantheon scene is good.
However, some issues need to be improved before release :
Stability : Alt-tab state still crashes occasionally. Also, dialog screens sometimes stall for minutes.
Multiplayer : Still doesn't work for everyone. For me and others, 3C is even worse than 3B.
Balance : Not nearly worked out. Skilled players will rip through it in a flash, the rest of the community will follow, and the demigod usage distribution chart will be very uneven. At least another month of intensive play with several hundreds of players is needed, with fine-tuning every week or two. If the game goes out like this, you will need to reset the pantheon rankings several times before the balance is settled.
Diversity : Many abilities and most items are currently not valid. So are most Citadel upgrades.
Pantheon : Not nearly worked out, and is not likely to achieve the lasting appeal it is supposed to create. The favor item system is still crude and with few good options. For example, the items could interact with style of play, map, and demigod type. The point system still needs some work. For example, there are points for damage inflicted but not for healed or prevented. Playing for the team rather than for a personal score is still a problem.
Here's hoping for a great game, Cheers
