    template_name ='games/list.html'
    context_object_name = 'all_games'
    model = Games

    def get_queryset(self,request):
        query = request.GET.get("q")
        if query:
                queryset_list = queryset_list.filter(
                Q(name__icontains=query)|
                Q(platform__icontains=query)|

from django.db import models
class Games(models.Model):
    name = models.CharField(max_length=250)
    platform = models.CharField(max_length=500)
    genre = models.CharField(max_length=100)
    language = models.CharField(max_length=100)
    image = models.ImageField(upload_to='Images_game',default='' )
  # def __str__ (self):
   # return self.Name

    class Game_detail(models.Model):
        game = models.ForeignKey(Games,on_delete=models.CASCADE)
        subcryption = models.TextField()
        publisher = models.CharField(max_length=250)
        date_of_publish = models.DateField()

    class Order(models.Model):
        person_name = models.CharField(max_length=24)
        person_surname = models.CharField(max_length=24)
        street = models.CharField(max_length=45)
        city= models.CharField(max_length=45)

You have a wrong signature of the get_queryset method. It does not accept request as a second parameter. You can access request from a self variable.

class IndexView(ListView):
    template_name = 'games/list.html'
    context_object_name = 'all_games'
    model = Games

    def get_queryset(self):  # no second parameter
        query = self.request.GET.get("q")  # get request here
        queryset_list = Games.objects.all()  # initialize queryset
        if query:
            # apply filter to the queryset_list
            queryset_list = queryset_list.filter(
                Q(name__icontains=query) |
                Q(platform__icontains=query) |
                Q(genre__icontains=query) |
                Q(language__icontains=query)
            ).distinct()
        return queryset_list

You can find more information in django documentation of get_queryset method
