Can't get dropdown list in mvc5 for a specil title

I'm trying to get better with asp.net mvc5 how ever I've ran into a problem. I've made Gamemodel where you can create games. On my post/create I get a drop down list for the games I've added on my Game model.

I also have my 'Title / Next game' I want a drop-down list on that as-well. But right now it just takes a string, but I would like a drop-down list like for GameId how can I achieve this ?

This is my Post Model

public class Post
{
    [Key]
    public int PostId { get; set; }

    //URL
    [Display(Name = "URL")]
    [StringLength(80)]
    public string Url { get; set; }
    //User
    [Display(Name = "User")]
    public virtual ApplicationUser User { get; set; }

    //Game
    [Display(Name = "Game")]
    public int GameId { get; set; }
    [Display(Name = "Next Game")]
    public string Title { get; set; }
    public virtual Game Game { get; set; }

    //Time
    private DateTime? _date;
    public DateTime? Date
    {
        get
        {
            if (_date == null || _date.ToString() == "1/1/0001 12:00:00 AM")
            {
                return _date = DateTime.Now;
            }
            return _date;
        }
        set
        {
            _date = value;
        }
    }

And this is my Game Model

    public class Game
{
    [Key]
    public int GameId { get; set; }

    //Game
    [Display(Name = "Game")]
    public string Title { get; set; }

    //User
    [Display(Name = "User")]
    public virtual ApplicationUser User { get; set; }
}
