Well, best of 2020 contains 5 turn based and 5 real time RPGs
To be fair, Turn Based, by itself, doesn't imply anything tactical. Most of the original fad of RPGs were Turn-Based, such as the Wizardrys and the like, Might and Magics, etc, but they were never termed nor are still really termed tactical.
The next fad, real-time with pause, is technically real-time turn-based and a bit closer to the concept of Tactical, but still not really what people mean by tactical turn based.
And it's not really only the fact that the game has turn-based combat that makes it a tactical turn-based, it's more that the game doesn't have much in the way of traditional RPG exploration type stuff and that one spends most of the game going from one set-piece combat to the next, and that the combat is then grid-based and locked within a battle-zone with no means to either flee and come back later or otherwise manipulate the encounter.
Traditionally, a Tactics game would shred out all of the general RPG stuff, like exploration, puzzles, small NPC non-combat side-quests, lore dumps and etc, and be called something like Fallout: Tactics or Final Fantasy: Tactics or X-Com. A genre that's always been part of RPG scene, but occupies a spot that contains lots of asterisks and would often be voted lower in years where more 'wholesome' RPGs are released.
They've always been very popular though, and there's never been a shortage of people who have wanted them to be "the same thing as an RPG" and deny any difference. Fallout: Tactics, for example, is game that turns up in many people's 'all time great RPGs'.
This site in particular has A LOT of X-Com fans, so this new trend will delight many here.
