Ok thanks for your feedback, so of what I have understood in my
gamescontroller.rb I will have the following:

def index
@games = games_relation.paginate(:per_page => 4, :page =>
params[:page]).search(params[:search])
end

in my game.rb file I will have the following:

games_relation = case params[:console].present?
when true then Game.where(:console => params[:console])
else Game
end

and in my index.html.erb I will have the following:

<%= link_to 'DREAMCAST', games_path(:console => 'Dreamcast')%>

please correct me if I am wrong. Thanks for your help.
