I can think of alot:
Just about every Sonic game I owned on PS2:This means like Heroes,Shadow,Riders,Rider Zero Gravity,I never found anything bad with these games,but I might have to play Shadow again to see if I still like it.
Pac-Man World 3:I'm still not really sure why people didn't like this game,I honestly loved it,especially the voice acting.
Crash Bandicoot:the Wrath of Cortex:this was my first Crash game,and one of the first games I ever played,and while I'll admit it's not the best Crash game,I still really enjoyed it.
Call of Duty:Modern Warfare 3:now here me out on this,it was one of the first FPS games I ever played,it was second online FPS game I ever played(The first being Black Ops,but I didn't play that long before MW3 came out)and I found it to be very fun.And for those who think the CoD series is the "exactly the same every time"I have a rant for you if needed.
