LeagueReplays.com offers a tool that allows the replay of League of Legends matches. Word is: "Matches are replayed within the actual League of Legends client, allowing full quality replays, with negligible performance impact while playing the game and file sizes much smaller than video. The camera may also be freely controlled while playing a replay, alowing [sic] the viewer to spectate [sic] whichever area they are most interested in." As noted by Games On Net, a huge thread on the League of Legends website discusses this tool, as Riot Games has long promised an official version of such a tool, but so far have not delivered, although they have also expressed concerns that this unofficial tool might be broken by future updates to the game.
