For a collector like myself who wants physical copy of everything, it just so annoying to have the same type of games with the same graphic and one said Tomb Raider and the other said Rise of the Tomb Raider. It just a small gaming pet peeves of mine. Don't mind it too much on movies since I don't really collect though but equally as annoying.
Then you get to the point where some games should not have a solid number like Far Cry 4 and Assassin Creed 3 and 4. They should be Far Cry 3.5 and Assassin Creed 2.5 and 2.6 respectively. Games should only have solid number when it a true sequel with updated game-play, engine, and graphics. But I'm guessing I'm opening up another can of worm at this point.
The numbering does bother me. Yes, a real sequel with a following number should be at least new engine, new assets, & moderately new gameplay.
Far Cry 4 should've been called Far Cry 3: (insert titular phrase).
Deus Ex did a good job:
Deus Ex: Human Revolution
Deus Ex: Mankind Divided
Same engine, similar assets, similar gameplay, just new 'levels'.
I'm a huge fan of Dota. Technically Dota 2 should've been just Dota- as it's now a true stand-alone game rather than a Warcraft 3 custom map. There's nothing 'sequel' about it in terms of pure gameplay- it's meant to exactly replicate Dota 1.
It's not a remake, it's not a port, it's most definitely not a sequel. What would you call it? I guess a closest would be 'remake'. But it's not remade anything, gameplay and heroes exactly mirror the original.
