So, I want to find a new fun PC game.

I want it to be the same as these games,

-HoN
-Runescape
-Warcraft

It can be both, downloadable or just online straight away from the laptop ;-o.
Thank You For Who Post!

Battle Realms WAS a game I used to like..And it is a bit like WoW

LoL - League of legends bahahaha. It's a HoN/War3 copy. Runescape... is actually pretty unique imo.

CrossFire.
Here's the download link.
And here is the forum link.

It's nice and it doesn't take up much memory on your pc. I suggest you playing it.

EDIT: Oh nvm. Just saw you actually wanted something like HoN, Runescape and Warcraft. And I can't delete this post, I don't know why.
But anyway, try CrossFire.

IMO you shouldn't try League of Legends
Its like hon for kids. No classic dota heroes, not balanced, you can't hold you can't deny, cartoony graphics.
If you're into strategy type or controlling just one hero you could try either a MMO or try Warhammer 40k

Heres a little list
-Cortex command(must pay for full version)
-GTA 4
-Assasins creed 1 and 2
-Aqworlds(browser)
-Phun(Physics sand box for me)

Dude, Try Diablo 2 Lord of Destruction [LOD is the Expansion set.]
Its an awesome game, even better that WoW in my opinion.

I believe he wants one that's downloadable/online.
Have you tried incredi-bots? It's a sandbox physics games where you build robots to complete challenges and stuff.
