1: this format is awful

2: you can use: binary, json, own format

most easier way is use json, easy to use lib here is Json for Modern c++

https://github.com/nlohmann/json

this lib is header only and you can just include file

there exist to json and from json, but not care about it now

just do proper serialize de-serialize of variables

std::string yourStringThatEntireFile = readAllFromFile(fileWithData)
auto parsetJson = json::parse(yourStringThatEntireFile);
for (auto& json : parsed file)
{
gamesClass object; 
  object.set... = json["variablename"];
    object.push_back(gamesClass); 
}

find guides about json format

idk, seems like basics for me, rly check some guides

while (gameData >> gameId >> name >> rDate >> rating) {
gamesClass game();
game.gameId = gameId;
game.name = name;
game.rDate = rDate;
game.rating = rating;
gameInfo.push_back(game); ive got this for reading the data into a vector but im getting an error that says 56 14 D:\Dtobe\Documents\project 1 cs.cpp [Error] request for member 'gameId' in 'game', which is of non-class type 'gamesClass()'

1. your syntax incorrect
2. use of stream unformatted incorrect
3. dont use unformatted streams at all
4. USE JSON IT EASY

;compile

class cl{};
int main(){
   cl obj(); // error
}```

You are redefining gamesClass object(); everytime in the loop. This should be outside of the loop. As a result, lastime you enter the loop you just have a final line in your object.
