I would say this - what game, upon immediate release to the general public or within a fairly short timespan afterward (no more than 2 years), was available on the on the most number of platforms.
The impressive part I’m trying to get at and understand is how one dev team releases a game for all sorts of consoles and system architectures all at one time. Like FIFA on GBA is an entirely different thing than it on XBOX 360 and I find that amazing that they can do that.
Madden 07 was released for 11 platforms - PlayStation 2, PlayStation 3, PlayStation Portable, Xbox, Xbox 360, Windows, DS, Game Boy Advance, Wii, Nintendo GameCube, Mobile phone
Also OP, how similar do the games have to be? Nothing immediately to mind, but I remember old handheld games that care e.g. overhead view while the console version was 3d. Or like Shadow of Mordor, which was AFAIK identical on PC, PS4, Xbox One, but had some features simplified for PS3 and Xbox 360. I think that might count but not sure of the former example.
For actual different games, it would probably not be a single dev team. Might not even be for the same game on different systems, if one is a port of the other.
The FIFA GBA team is almost certainly different from the XBOX 360 team. And I’m pretty certain all they did on the PS2 version was tweak the rosters and change some superficial characteristics of the players (like maybe giving them the right skin color, hair color, and height–fairly easy to do without having to do any model work.)
This slipped under the radar, but I’ve been looking and it has been on an impressive list of devices. There’s been an official Worms(*) game on the following:
Amiga
CD32
Game Boy
Megadrive/Genesis
Jaguar
Mac
Dos/Windows
Playstation
Saturn
SNES
Dreamcast
Nintendo 64
Gameboy Color
BeOS
Gameboy Advance
N-Gage
Nintendo DS
PSP
Wii
Random JavaME Devices
Playstation 3
Xbox 360
iOS
Android
Linux
PS Vita
Playstation4
Xbox One
Playstation2
Xbox
Gamecube
(*) As in with the basic Worms gameplay, not one of the spin offs.
Mortal Kombat’s principal rival (at the time, at least) Street Fighter II was released on:

If we’re talking within 2 years of release, Lemmings was released on 16 different systems between 1991-1993. Plus an arcade version that was developed but not released.
We need the OP to clarify. Do the ports have to be identical? For example, Killer Instinct lost a substantial amount of content when ported from arcade machines to the SNES. There is a Reddit thread where someone suggested that the port has to be done by the original studio, rather than a third party developer (which is why Tetris wouldn’t qualify.)
ETA: the Amstrad CPC was a British rival to the C64. Eventually Amstrad was squeezed out by Commodore completely.
Although subsequent posts show this isn’t exactly what’s being looked for, my first answer to this was “Blackjack”. I don’t think there’s any device with even rudimentary calculating power that hasn’t had a Blackjack game implemented on it at one time or another, since it’s a very straightforward set of rules for the computer to follow, but it’s still a recognizable and fun game for the player. (For some values of “fun”.)
Even the more modern video game systems probably have a “100 Casino and Family Games” pack out there somewhere with Blackjack buried in it.
As a guy who used an Amstrad in High School, it was just an IBM clone but from Europe that had the PC power in the monitor and a prehistoric version of Windows years before MS came out with one.
Nope, there were many different Amstrads. The early ones (the CPCs) were not PC compatible, were standard 1980s z80 8-bit and were unusual for the time in that they had a built in tape player or 3.5" drive:
Later Amstrad did PC compatibles and (I believe) dedicated word processors.
