As a casual gamer I have enjoyed playing 'Rift'. The game is easily soloable and there are still alot of players on the EU servers should you wish to join a guild or party up to complete quests or dynamic events (rifts).
The PVE is nothing new but still very enjoyable. The quest hubs lead you from one to the next and the nice thing is that you dont stay in the same area for too long. There is little grinding and by completing Rifts and the occasional PVP match I have never found myself underlevel.
The are hundreds of achievements to collect and this adds to the enjoyment of the game and gives plenty of replayability.
This edition of the game comes with a free mount and also the added 10 days of gameplay (40 on total) making it much better value than thwe standard edition.
This is a nice filler game until GW2 or others come out later in the year.
