I would say that they are. Cities Skylines is not just better than Simcity - it is the nostalgic version of simcity that I remember from my childhood. It actually lives up to those inflated expectations. It is a huge improvement on everything that has come before it.
GTAV is proving to be a lot of fun, not just flashier graphics but the gameplay is a lot more satisfying. The cutscenes seem to have improved a lot as well, some of them have made me laugh out loud. Unusual for a game storyline. Farcry 4 was a lot of fun. Both focus on emergent gameplay a.k.a "dicking around to see what happens".
If you like strategy then the Paradox catalogue is well worth a look. Games of that depth didn't exist 20-30 years ago. CK2 and EU4 are a lot of fun to play, and very engrossing.
