Quoted from Rarehero:
They’re better games. WOZ had different and new tech, but fundamentally a game isn’t tech...it’s a game. Games will be judged on fun and gameplay. Outside of the nice service menus, lighting and LCD, there’s nothing that innovative. Games have had up/down toys, spinning things, and doors that open forever.
Technology though opens up new gameplay and choreography options for programmers to take advantage of and that's exactly what Keith Johnson and the team at JJP did so well with WOZ. WOZ may have some similar moving mechs of past games but those games from 20 years ago don't have anywhere close to the same amount of programming applied in terms of mode choreography, depth, utilizing RGB GI + RGB insert lighting, integrating LCD animations with HD video clips, etc.
A games programming and mode choreography are what ends up bringing a layout alive and from that fun gameplay is born. Without the tech and the programming all of these games are just a box of lights. This is why a rather minimalistic game such as TNA is considered so good as the programming and mode choreography is excellent.
