I bought this game a long time ago for a decent amount of money, but since it's a long game, I postponed playing it... Until recently.
Many of the "recommended" reviews here are from people who spent a very, very short time playing Avadon. Had I written such a review when I was only a couple of hours into the game, it would have been positive, too. It was very fun at the start... but then it became profoundly NOT fun.
You see, early on, you have a couple of quests and a couple of locations. You have various characters, you find items, battles are nice, you get better loot, your characters work in synergy... And then the game suddenly becomes a chore. Quests pile up. The quest texts never get updated. There are no indicators anywhere about the people you need to visit or return to. No indicator of what you need to do. I spent a lot of time going around and talking to people, only to find out that a quest isn't over. The loot doesn't scale up. Your damage doesn't scale up. And the game difficulty (I played on "normal") suddenly switches to "most frustrating game ever". You die. You die a lot. You are too weak. You need luck with the RNG, and you need potions and scrolls in greater amounts that you can obtain. Your abilities are on a large cooldown. Again, not enough potions to alleviate that. To add insult to injury, you spend vitality on abilities and vitality *does not recharge by itself*. You need to basically go back to the Avadon fortress on a semi-regular basis. There's no real quick-travel system, so every time you want to do that, you're looking at about five wasted minutes.
About 15 hours in, I seriously contemplated quitting right there and then; but I said to myself "you spent more on this than on many other games, so you NEED to finish it". I had a quest to follow a warrior into the woods and clear out some spiders. "Some" turned out to be about four nests of four to five spiders each. They were teleporting spiders which cast corrupting spells and thus did a lot of damage-over-time. Took me an hour to finally win that sidequest. Okay, I said, this is one of the harder battles; let's continue. Then I found what was an almost unbeatable Shade. Somehow managed to get that done as well. Then I found an evil Drake that spawned minions *and* mind-controlled several tough soldiers (EDIT: forgot to mention that it was HEALING those soldiers, so every time you came close to killing one, it would be healed to max HP; repeat 4-5 times, while your characters die and you've spent all of your potions). That... that was unbeatable, and it was the turning point at which I resorted to cheats: bumped my characters to level 30, then constantly used healing, shields and ability cooldown reset.
I gave up on the sidequests. I have no idea where I found most of the people and what I needed to do next (again - the quest system is extremely rudimentary and doesn't tell you anything). Even with constant cheating, it took me a total of 40 hours to finish the main story line.
Disregard the "recommended" reviews, honestly, and check the achievements:
Only 1/3 of the total number of players met a certain NPC called Redbeard, and that happens *very* early into the game.
Only 1/50 (a measly 2%) of the players finished Avadon. Two percent. Wow.
You see all those <40hr reviews? Yeah, they recommended a game they never finished. If it's so fun and great and awesome, why did they stop playing? Because of the issues I mentioned here. Let's not even get into "OMG BEST GAME EVER!!11" reviews from people with 1-5 hours in.
Skip this. Honestly. Even if you get this in a bundle, it's just not worth playing. Get an RPG that's actually fun.
If you *do* feel masochistic and try to play without cheating, I'll give you a tip: in this game, Dexterity rules. Get it to a minimum of 25.
Highly not recommended.
