1) There are 20 'classes', but they are more like frameworks by which to spend your DP (Development Points), making it mostly point buy. Each class pays a certain amount for certain categories of abilities, and are also (In the case of Primary Skills like Combat/Magic/Psionics), can only spend X % of their DP there (I.E. A Warrior can spend 60% of their DP on Combat stuff including Attack Block/Dodge (Whichever style of defense you choose), Wear Armor, etc.), a Wizard can only spend 50%, and would pay 3 DP for every 1 point of Attack, say, where a Warrior would pay 2 for every 1. You can put points wherever you want, but some classes are better at it. (And if you wanted to really invest over multiple areas, you can use the hybrid classes like Warlock (Warrior/Wizard), Warrior Mentalist, Warrior Summoner, Shadow (Warrior/stealth type)...
Secondary skills (Hide, Swim, Persuasion, the usual stuff) are grouped into categories and priced in a similar fashion: A Thief can get 1:1 in Subterfuge skills, where a Warrior gets 2:1. You can use Advantages (Which your character gets 3 points worth, plus more if you take Disadvantages) to buy down the cost of certain Secondary skills/skill groups (among many other things). 2 Advantage points, and (for example) 2:1 Social cost for a Warrior can be brought to 1:1. 1 Advantage point, and you can reduce the cost of a single skill. So its all in all a pretty flexible character building process.
2) Damage is not 'omg big numbers' like Final Fantasy, and combat can be fairly fast paced and vicious. At 1st level, you'll see ranges of 80-120 LP, and most things will go down with 3-4 solid whaps. Degree of success in your attack roll versus their defense determines how much of your weapon's potential damage you do: Things like a Two handed sword have a base damage of 90, and can be extremely painful if you take 100% or more of the weapon's base damage (caused by them beating your defense by 100+. If it was something ridiculous, like 400, you'd take x4 the base damage). Criticals happen whenever you lose half your current LP in one swing, and those can lead to nasty penalties.
3) Here's an example first level character I had lying around, pasted behind the cut. There may be a few errors, as he was done awhile ago and the values aren't recorded, but it should give you an idea what it looks like laid out.

The actual character sheet is visible on the website.
I've been looking at it and was wondering if it's class based like D&D or point-based like say Mutants & Masterminds? Is it like Final Fantasy in regards to damage dealing and stuff like that? What does a sample character look like? I hope you can answer my questions
