Even in in the case of say, Tekken 1 and 2, while the movement is stiff and moves are limited in T1, there are some crumbs of gameplay and moves [Mishima's WGFs, Paul's Death Fist] that were there from the start before Tekken 3 gave it a facelift and new pair of pants to make it THE first Tekken to take the world by storm
That's why I never play Tekken 1 and 2 but Tekken 3 was so popular here in India when I was growing up. Now, it makes more sense.
Tekken 3 back in the day was such a gigantic leap in quality that it makes sense why it ended up becoming known as a legend in videogame history - and nowadays even if it may be a tiny bit primitive or lacking in characters/moves compared to later games [but absolutely not for the time] it still holds up swell because it is the first foundation of modern Tekken after all, which would become refined the most with Tekken 5.
Thanks for reading and for your comment :]
