Path of Exile Review (Sephrinx)
I don't have a lot of Hours on this, as I just started playing it through steam. I have been playing Path of Exile since June of 2012 
It is among the most amazingly awesome games I have ever played. Coming from Diablo 2: LoD, and the various mods (Valhalla, Eastern Sun, Median, etc) this game is perfect for me.
* I will start here, with the things that I enjoy about it.
1. Diversity among builds. Want to shoot a thousand exploding arrows per second (Quill Rain + Chain/Greater Multiple Projectiles/Exploding Arrow/Fire Penetration)? Want to blast rays of fire that launch exploding balls of magma (Scorching Ray/Cast While Channeling/ Fire Penetration/ Multiple Projectiles/Magma Orb)? Want to call forth the fury of the heavens with a mighty scepter, smashing your foes into submission (Mjolnir+ Lightning Strike/Arc/StormCall/Spark/Multistrike)? The sheer amount of ways you can go about destroying mobs is limited only to your imagination.
2. Story is great, very interestnig, and keeps you entertaining while playing through the game. Unlike other ARPGS of similar play style, Path of Exile is able to effectively deliver a quality story along with the extremely well done gameplay.
3. Scenery is dark and grim, gloomy, morbid, and full of gore. From corpse ridden beaches, ancient temples filled with undead and skeletons, destitute crumbling cities, palace cellars flooded with blood - ridden with heaps of corpses and twisted miscreations, echocing crystal caverns of golems and mutated freaks. The variety in enemies and terrain is very broad.
4. Item creation, map alteration and creation, uber dungeons. There is plenty of challenge to be had in this game, thus keeping you striving to achieve ever greater power and push yourself ot the absolute limits of your capabilities.
5. Infinite replayablity. I have made probably 50+ characters so far, and each one gets progressively more powerful as I understand more about the game, the mechanics, and how to build them effectively.
6. Temp Leagues + Ladder. Nuff said.
7. Constant expansion and content updates. The game is constantly being updated, minor balance tweaks, additional items, skills, monsters, maps, etc. It's amazing.
8. Grinding Gear Games are among the most amazing gaming company. Really really good people and they constantly interact and have dialogue with the playerbase. "How do you guys feel about X? Does Y feel right to you? If you could change X, what would you do and why?" etc.
I could go on for another thousand lines but I feel as though I got the point across. The game is amazingly fun and addicting.
Now, for the things that, I don't necessarily "dislike" - but things that I feel may dissuade other people from playing the game.
1. Learning Curve is incredibly steep. Your first 3-5 characters will be absolute trash. You need to do a bit of research on what to do and how to build effectively, otherwise you're probably going to get wrecked hard once you get to a4 merciless. Here is a beginners guide - https://www.youtube.com/watch?v=lEZtq6FSebE&list=PLjlRwdIo6SixoG_Bo5bhKCzZtOMVuVnJZ&index=8&t=8s
2. Repetition of acts, 3 difficulties (however, this will be gone come July - TEN ACTS ONE PLAYTHROUGH HYPE!) Going from Normal, to Cruel, and then to Merciless can really put people off. Myself, I'm used to it and have done it since d2 so it's just a normal thing for the arpg genre. GGG are going to change that though.
3. Item crafting is extremely expensive. Like, unfathomably expensive. I have never crafted an item before other than throwing an alch and a couple chaos into a rare item.
4. Currency is nightmarishly rare. I've found maybe 4 exalted orbs in my entire time playing this game. Two of them were just within the last week as well. I have only ever owned two 6-link items. Wings of Entropy, and some random rare 2h sword that is garbage.
5. poe.trade is the only real way to trade. $Chat is a scam 100% of the time. Once they implement a real trading system other than posting shops online and checking the forums every 3 minutes, or browsing poe.trade for an hour at a time trying to find an item to fill a hole in your build this game will be just shy of perfection.
Those are really the only negative things I can think of that might dissuade a player from sticking around... the game is magnificent.
I highly, highly suggest you play.
Overall Rating
