Foopets vs Neopets
Foopets
Foopets is an amazingly realistic, free-to-play pet simulator that you can play directly from your browser. Although you'll start off with a random pet, you'll eventually be able to adopt the pets (onloy dogs and cats for now though) you actaully want, be it a Tabby or a Husky. Your virtual pet on Foopets is almost like having a real pet in many ways. You'll need to take it out for walks at least once per day, and of course you'll also need to feed and bath it regularly, shower it with your love (and treats), and buy toys to play with it. The best part about this game though is definitely the realistic reactions that you get from your pets.So, if you have always longed for an actual pet but you can't possibly have one due to whatever reasons, Foopets will be able to fill in that gap and give you a beautiful and adorable fluffy virtual companion to love. You'll love it!
Neopets
Neopets is rather old yet entertaining simulation/virtual world game that lets you adopt and take care of magical and unique pets. This means that you'll be expected to build them a home, buy them food, clothes and other cool stuff. Set in a cartoonish and immense world, you can even set off on exciting adventures with your pet. Best part is that thepets in this game can grow alongside you and they have different looks for different stages of growth, much like the Pokemon in a Pokemon game. There are plenty of fun mini-games to keep you engaged for hours on end as well.
Although the game is a bit on the old side (being released in 1997 and all), the game still holds its charm for players who want a game that's a combination of a usual pet simulation/collection game with a virtual world game. It's free to play and you can play it directly from your browser!
