Topic: Do you buy The same game on two different systems?

I avoid it as much as a possibly can, but I've succumbed a couple times.

Rocket League
Mario Kart 8

And if you count remakes:

Ocarina of Time
Majora's Mask
Okami
Super Mario 3D World

Alot of these, I've sold the original copy, but not rocket league, because both are digital. And not Ocarina of Time or Majora's Mask, because I'll always want to play the original too.

i have never own 2 game simultaneity on different system, but I have re-bought often remastered I have already played in the past on different system (skyrim,diablo 3, alien isolation ..)

It happened, I even have some games doubled or tripled up on the same system! E.g. old CD version of a game, then later a DVD version and then on Steam and/or GoG.

Not very often, and if I do its usually years apart where the advantage is more powerful hardware and/or new features. There's a fair few PS3 titles I bought whilst I didn't have a decent gaming PC, which I then 'upgraded' to the Steam editions (after building said decent gaming PC) to enjoy in nice shiny 1440p 60fps. But even then, I'll usually only pick them up a second time in a sale. Mostly turn-of-the-decade and early-2010s stuff like Bioshock Infinite, Alien Isolation, Tomb Raider etc

I don't think I've ever bought the same game twice on different platforms at the same time though - I'm not a games collector, so that seems kinda pointless.

Depends on the circumstances. The general rule is that I will normally buy only 1 copy of the game on my platform of choice. However, sometimes I make exceptions.

The most common reason why I might own it on two different platforms is that a year or two down the line, the games happens to be on sale for extremely cheap so I snag the copy. This is more often than not purely digital games and indies such as the Steamworld games because physical games don't normally get so cheap, though I do sometimes buy physical games on more than one platform for the same reason.

The second main reason I might do it is normally because the game is just that good. I brought P5 Strikers on PS4 (I mean, I also own P5, P5 Royal, P5 Dancing in Starlight, so realistically, why would I not choose PS4 over Switch, might as well complete the collection on one console). But anyway, I loved it so much that I thought "you know what, this game would be great to play through on my Switch at a more leisurely pace". Sure, performance wise, it won't be as smooth at 30fps, but it seems stable enough. Another game I love a lot is Ocarina of Time; I own it in at least 4 different ways; N64, Zelda Collection and Wind Waker Limited Edition (baring in mind that I did not own a gamecube until after I owned a Wii, yes I know it's stupid, don't judge me) and the 3DS remaster. Shovel Knight I own on both Wii U and Switch.

Yes, i did.
I have triple dipped LEGO CITY UNDERCOVER (Wii U = 1st, Switch = 2nd, PS4 = 3rd).
And i have finished the storyline for All those version.

Yeah, 3D World on wii u and 3D World + on the switch

Yep, done it a few times on Switch. Have Doom 2016 on Xbox and Switch (the former mainly for multiplayer), and Rocket League on PS4/Xbox/Switch. Always at sale prices but sometimes I find it really convenient.

The Resident Evil games some of them last month ive bought from the eshop for my Switch Lite.

Never had Resident Evil 5 before years ago but bought it along with Revelations 2.

also Resident Evil 0 and Resident Evil Remake I have for my Gamecube but getting them for my Switch Lite i can play them on the go or whenever.

Besides its a pain to switch back and forth from an old 19 inch Sansui tv with my Gamecube hooked up to it and back to my Vizio tv since I cant even hook my old Gamecube up to my Vizio tv anyway

No I don't usually. If I have played it on one system, I won't buy it again on another simply because I have other great, new experiences to have. Unless it is an all time classic though.
