What Ace of Spades needs .. is a ability to track kills, killstreaks, and the sort.
Now, you might wonder, about what the hell I am saying, and so, as a result, I have to painfully explain to you about what I mean.
If you go to a server and get like, 197197319371973193719731937 kills, it will be recorded and if you join to another server, it will say how many kills you have in total. It will tell me how many headshots I have in total, the most kills and headshots I ever had, and what was the highest killstreak you ever had. If you want more, it will show you the weapon that you have used the most, how many blocks you have placed in the past few years, and how many grenades you have thrown. The thing will be hard coded so noobs cannot make themselves look awesome because they have had 7597575925692856295629562956257926578265827356827562785627856285628756278562785628756257862578265782658 kills over the past few days.
It will also show how good you are in the game, depending on the ratio of kills and deaths you have had, so other people will know how PRO you are.
Good idea, hmmm?
