Without going into too much detail, Demon's Souls is by far one of the greatest games I have come across. Many months ago, I was a bit reluctant to buy it after having purchased many games in a short time span, but I was very glad when I finally purchased it.
The game is challenging, but not too challenging. Learning the ways of the enemy is key in helping you progress. Leveling up using souls you have collected can make you withstand more hits, carry more items, have increased stamina or cast more spells, but picking a base class at the start of the game doesn't limit you to what you can do.
Dying, will no doubt happen very often, but that isn't the end of the game. It actually helps you because it allows you to learn from your mistakes. If you die, you lose your souls, your means of leveling, your currency for trade, etc, but if you can manage to make it back to your blood stain, then you can reclaim the souls you lost. If you die on the journey to your blood stain though, you lose the last lot of souls you were trying to reclaim and drop any you had picked up on the way. You can however, travel to that last place to pick those up, collecting more souls along the way, but if you die, the cycle continues.
There are 5 worlds, but multiple levels within each and though I haven't had the game long, it is not linear, in the sense that you have to complete each world, from 1-5. You will need to play through World 1 - Level 1 and defeat the first boss, after which you are free to roam all of the other worlds in any order you please. You will likely find yourself replaying the same levels a few times over, but this isn't boring because you may have to go back to find other paths or things you have missed, which in turn can provide you with more demon's souls, extra NPCs in which to buy from, or information which can prove useful in your progression. The game isn't obvious either. The levels themselves may seem linear in structure, but the path to progression is not simple. You can end up finding it difficult to proceed through locked zones, but when you finally get round to doing so, the satisfaction of your achievement is well worth the effort.
When you defeat demon bosses, it is advised to hang on to these special demon boss souls instead of consuming them and adding them to your pile of currency-like souls. At the start of the game and through many of the worlds first levels, NPCs will happily accept any souls as currency. However after a while, some upgrades, spells or miracles will require only demon boss souls to obtain. You do not drop items on death - other than your current souls - but non-consumed demon souls from bosses, or lesser ones found lying on dead soldiers will be safe for use at another time.
The combat on this game is superb. Weapon wielding is great. Using the shield is very helpful, and whilst stamina plays a part in how effective both weapon and shield are, it recovers very quickly. It's incredibly well designed and the lock on system makes combat easy to use, but the battles themselves are obviously not a walk in the park. I haven't used magic yet but it's going to be pretty similar.
Graphically the game is amazing. It's a fantastic third person RPG, with a good challenging difficulty, which to some may seem overwhelming at first, but once you get into it, you will manage. The frame rate at times can become choppy but the PS3 handles the game very well - for the most part the game is as fluid as anything.
When you've completed the game with your first character, the game doesn't end. You get to NG+ (New Game +) which increases the difficulty of the foes, but lets you keep a few things from your previous play through.
I'd advise only patient players buy this, because this may be why Demon's Souls has bad ratings by some people. It's not for cry babies, or for lovers of games who play themselves. It's a mans game - or womens ;) - and the difficulty, an unapparent progression make this challenging RPG a fantastic play through.
Those of you considering purchasing this game, who are worried about difficulty, should check Gamespot.com's review of Demon's Souls. Those who are considering Dark Souls, I suggest they get Demon's Souls first.
9/10
Enjoy!
