Dead Island is a good game, but there are many reasons I can't recommend it to my friends.
The challenges dishing out XP is interesting and all, but with the tally accumulating for all characters, you can run across ridiculous scenarios of a brand new character suddenly going from level 1 to level 12 before leaving the prologue.
The UI has some serious issues, especially the way weapons are picked up and/or replaced.
Throw your weapon, go to retrieve it, and potentially end up with half a minute of inventory shuffling.
I would have been happier if there wasn't a "replace" option at all, and you simply can't pick something up if you have no room in your inventory. Would solve a lot of problems (especially for the yogscast, lol).
Finally, it's obviously a console game .. apart from mouselook (which is awesome, by the way. Here I'm referring to the sensitivity slider and general responsiveness), managing weapons was a chore.
Assign numbers to each of the positions on the wheel. People can still use the wheel. They wouldn't have to press numbers if they don't want to. That's how little it would take to turn a shitty UI into a decent one.
Multiplayer is a bit of a mess, the way quests and level scaled zombies are managed.
Sure, it's fun when a level 35 guy joins my level 6's game, and the characters are equally proficient at beating down zombies ...
Ok, the level 35 is a little better with melee and guns, but the level 6 can kill anything with a single molotov. It balances out, right? What it does is make no sense.
I'm not even going to get started on how the loot drops happen.
Obviously, this isn't an issue if a group of people only play the game with each other, but then how's that different from having no level scaling?
Then there's the voice acting, which can be vomit-inducing depending on how familiar you are with the supposed accents.
As a chinese-australian, it was bad enough for me to skip most conversations and cutscenes.
Just one example - a fresh off the boat chinese should not be voiced by a vietnamese. Just sayin'
The game is a lot of fun, but from the perspective of a 1337 gamer who picked up the game without any expectations, it's nothing special.
