Well, while there are a lot of games from franchises that I enjoyed, a lot of the other installments are ABSOLUTE SHYTE (I'm looking at you, COD). Here are the franchises that rarely, if ever, let me down:
-Assassin's Creed (I even liked the Android game!)
-GTA (Brilliant, brilliant games)
-Pokemon (Almost perfect, 'cept for Ranger and Mystery Dungeon)
-TES (I still can't get the opening theme out of my head... "Dovahkiin, Dovahkiin, Naal ok zin los..."
-Fallout (Really enjoyed the first two and tactics, and Bethesda delivered with the third installment)
-Batman Arkham series (I know, only two games, but still, it's Batman!)
These franchises have continued to deliver, and I can't wait to play future installments!
