Neopets vs The Sims Mobile
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!
The Sims Mobile
The Sims Mobile is possibly the closest you can get to getting a free-to-play version of The Sims and although you are limited in certain aspects as compared to The Sims Freeplay, you can do so much more in this version. The Sims Mobile has a lot more "life simulation" in it, allowing you to craft your own family legacy and pass any family heirloom (or any other distinctive characteristics) on from generation to generation. Not to mention, you will also be able to do the usual Sims stuff like picking up a career, party with friends, build a home, fall in love, get married, start a family and more.The Sims Mobile is poised to take over from The Sims FreePlay and will let you dive into the a life simulation that's much more in-depth rather than being just a social virtual world with avatars.
