I'm no massive Blizzard fan, nor am I too great at RTS games - but Warcraft III is simply a must have!
Sure, the graphics may be a little dated and it can take a while to get the hang of the game's mechanics, but once you do, the pay-off is phenomenal!
You will have at-least one-thousand hours of (guaranteed) fun with this title!
Frozen Throne's a helluva riot too, think of it as the kind of DLC you just don't find any-more.
The kind that provides you with actual content, considerable updates to the game, a new storyline to entertain you and so on (not just entirely cosmetic differences or an overrated horde-mode).
Overall, this game is well worth then ten quid, and as my title states: it's a true PC gaming classic!
(SIDE NOTE: Multiplayer spawned the incredibly popular MOBA genre with the game-mode, Defence of the Ancients. So yeah, guess you could say Warcraft III's pretty big news).
