yes, arcade games and DL content cost money to buy. The arcade games all have free demo's that you can DL to see if it is worthy of a buy or not. MOst arcade games are 400 or 800 MS points, (400 pts = $6.25 US).. a few games cost 1200 points. Most game content (extra levels, features, game types, ect.) typically cost 800 pts.)
I think I have 3 arcade games which were free through temporary 'give aways' upon release. after a week or so they upped the price to 800 pts... so if you snooze you lose.
You can also buy Tv shows and rent movies in HD, but they are overpriced and generally not a good deal at all.
I pay 50 bucks per year for my gold account which allows me to play online multiplayer too.
