Why does it say I played in 248 games but I only have 229 completed?

Maybe because "Games Completed" only means multiplayer ranked games.

Just guessing though.

I don't think so cause to the best of my ability I can't remember playing in any practise games ever

There are several reasons why a game won't show up under the "Ranked Games" section:

- If it was a practice game
- If the game hasn't finished yet
- If the game was ended by vote
- If the teams were uneven

any vote to ends?
and i think it also includes games you were removed/declined from while being directly invited, or games for tournaments that you started.

go to my games and select all games

I just checked it, and I think i was wrong.. my played in, and all games are a good 40 off, so that should be tourneys i started and declined games

I VTE games for lots of various reasons
