There seems to be confusion about the chronology of the series.
IMPORTANT: Generals does not count since it is a complete spinoff.
On with the chronological order of games:
- Red Alert - Can be seen as a prologue to the series as it shows us Kane.
- Red Alert 2 - Even though Kane is absent from this game. Yuri shows the Soviet commander a photo of him with Joseph Stalin that was taken possibly during the Second World War. In Renegade, a picture of an Apocalypse tank can be seen in Cairo, inside the Temple of Nod. This highly suggests that Red Alert 2 was part of the series.
- Tiberian Dawn - First game to feature Tiberium
- Tiberian Sun
- Tiberium Wars
- Tiberian Twilight
Red Alert 3 is not part of the series since it was designed as a "what if" game.
What do you think? Are there any games I missed?
