LarryLaffer: It's not like Diablo. Let me tell you why.
1. ArenaNet (a very talented team, some ex-Blizzard guys that worked on WoW for a while, Starcraft, Warcraft, Diablo .. you name it). They are constantly in contact with the alphas and the community, giving us access to their commands/servers, joking with us and are overall really cool people. I can't name a company that is cooler then them.
2. No grind, skill matters (if you haven't played a real 8vs8vs8vs8vs8 Tombs map or GvG you don't know what GW PvP is all about). Teamplay is very important. The fast-paced PvP reminds me of FPS clan fights a little.
3. The skill system that somewhat resembles Magic: The Gathering. 450+ skills but you can only build a deck of 8 and use them in connection to your character specification and specializations. Also building a good solid team build with 64 skills that covers most of the tactics and anti-tactics requires a lot of planning.
4. Streaming tech that downloads the game assets as you play the game. Brilliant! Fast bug fixes and exploits, new material,…
5. One of the best looking online RPGs to date.
6. A great single player story that will continue with chapters / expansion packs. Jess Lebow is the author (Baldur's Gate I and II,...).
7. Great network code. Runs and plays smooth like a baby po-po. Build for people with crappy connections.
8. No downtime, since multiple instances of servers can be run. They take some down and in the mean time you can play without interruptions.
9. No shards / realms. A global PvP/GvG network. You can switch to international districts with just a few mouse clicks. Real world-wide tournaments and GvG battles.
10. No monthly fee and you can still play with friends who have bought an expansion pack you didn’t.
This and the game is fun!
