Agree with Ponydragon. Minecraft for sure. Most disappointing games I've played are Star wars battlefront 2 (2017). The originals were great!!
Fable 3. The first game in the series was far superior in my opinion
GTA V. Decent but couldn't get into it enough to finish it when it first came out havnt touched it since.
Neverwinter nights 2. Hyped up to be a competitor to Oblivion. Not even close. Not even comparable to NWN 1 which still holds up today and has a large fanbase .
