I think the most important things to know of PoE are that although it is very well done it is very difficult and unforgiving with a steep learning curve and strategy that will follow you all the way through the game. I feel it is designed for the die-hard ARPGer familiar with this type of online only game. Although you can play solo you must be logged in at all times. I played fairly well up into level 38, into Act 3 (the last act), but the strategy and planning necessary got the best of me. I'm more adventure and action oriented and I like intuitive games. PoE is not intuitive!
If you are bad at strategy and ARPG that are not intuitive to play then 4--Poor is a fair rating. If you love this style of game then 8--Great and above is a fair rating.
The game is all done in real time--even while pausing solo so you must plan where you park your PC before you take off for the bathroom or a sandwich. And worse, if you portal back to town and do not return within around 8 minutes or so iirc the whole dungeon area you might be struggling through gets respawned which will include a new map and respawned monsters and foes. So for your little venture back to town you get to start the area you were in over again--lots of fun. But if you are into 'farming' this isn't an issue and when you get the hang of it you will manage.
