Honestly never really cared much for online/web based services related to games, most popular probably being battlelog, it doesn’t really add much but… another nuisance. However, the one thing I’d… want, I guess. Would be something in similiarty to QLRank.com 's individual player profiles (such as: http://www.qlranks.com/duel/player/evil ) that add the ability to (in most cases, not entirely sure how they handle it… I suppose private servers being the exception) review demos, map distribution and recent games. As for recent games/stats, please… display all the information, no one really cares to see who’s had the most damage given or best K/D, or highest accuracy, take an example of ET and RtCW’s community made gamestat parsers (albeit not the gamestv one :P). They list in excruciating detail to whom you died, when you’ve died, by what weapon, damage given, received, gibs, kills, deaths, efficiency, revives, favourite weapons, etc. etc. etc on a per round and total basis.
Such as these for example, one featuring a total stats for all maps and rounds played, the other a specific map on a round to round basis:
