Microsoft’s generally pretty forthcoming with list of how well digital titles perform on their Xbox Live service. Sony’s a little less so – so we rarely get to see how well games are doing on the PSN – but Sony has provided a list of the ten best-selling PSN games and downloadable content on the service. what’s come out on top? The answer might surprise you.

Here are the top 10 best-selling PSN Games of 2011 (digital games only, not full PS3 games):

1. Tetris
2. Resident Evil 4
3. Infamous Festival of Blood
4. Back to the Future: The Game – Full Series
5. Dungeon Hunter: Alliance
6. Castle Crashers
7. Limbo
8. Battlefield 1943
9. Mortal Kombat Arcade Kollection
10. Magic: The Gathering – Duels of the Planeswalkers 2012

Tetris? TETRIS! Look, I know the game is an example of genius design, but why the heck is it still so damned popular? I thought people only still played it on mobile devices because it gave them something to do whilst on the toilet. I’m also not particularly happy about the re-release of Resident Evil 4 being there. Sure, it’s a great game (one of my favourites from the last gen) but it’s a horrible, scaled up, piss-poor port that Capcom’s trying to peg as an “HD” remake. I’d also hoped Limbo would have featured higher, but at least it’s in the top ten. I haven’t actually had a chance to try out Festival of Blood…but I like vampires (real vampires – not that sparkly nonsense) so I’m keen to give it a go. What PSN games did you play last year that seem to be missing?

Below are the top 10 Paid Downloads:

1. Call of Duty: Black Ops First Strike
2. Call of Duty: Black Ops Escalation: Content Pack 2
3. Call of Duty: Black Ops Annihilation: Content Pack 3
4. MLB 11 The Show Road to the Show Training Points
5. FIFA Soccer 12 Premium Gold Pack
6. Call of Duty: Black Ops Rezurrection: Content Pack 4
7. Angry Birds (PlayStation Mini)
8. FUT – Premium Gold Pack
9. MLB 10 The Show Road to the Show Training Points
10. FIFA Soccer 12 Premium Gold Jumbo

Weird that angry birds is considered DLC and not a “game,” but no real surprises otherwise; Call of Duty reigns supreme.
