Review
Pros
1. Complete classical shooter experience - You can carry all the guns you find, your health doesn't regenerates. I played it 6 years after it's release and still found it intriguing.
2. Loot - There is a lot to find and collect.
3. In the beginning you find yourself always short of ammo, forced to kill by melee many times but as you start finding new guns ammo was more than enough.
4. Good storyline, also some role playing elements.
5. Lot to explore - There are always lot of areas where main story doesn't requires you to visit but you can if you like exploration in a game.

Cons
1. Can be considered a horror game but it won't scare you neither it aims to do so.

Review
Pros
1. The funniest game I ever played.
2. Overlord keeps on getting more and more better as you progress through it except for the 2nd and 3rd hour where I felt that it is getting old already. But the rest of it is really good, new areas new enemies and new minions keep the game interesting all the time.
3. Choice of selecting the task/mission you want to do first, something you usually find only in RPG games.
4. Strategy - Different enemies and changing environments mean that neither brute force will work nor one strategy that worked for you earlier. You need to keep on changing as per the situation.

Cons
1. Glitches - Most of the loot is in secluded corners where your minions go and bring it for you or themselves but it was usual to see one or two of them getting stuck there.
2. Game has large areas with your tasks scattered around it, lack of map really feels sometimes. A map could save you from needless wandering around in case you miss something.
3. Attack is assigned to a button to which Skip cutscene/Action/Fast travel are also assigned. e.g. In one of the mission which was about to finish enemy spawned near fast travel location, attacking him I fast traveled back to castle and coming back to mission location means doing the whole mission again.
